Driving along with no problems then when I pulled up outside a friends house and dropped something off the glow plug light started flashing. Thought I’d best not turn the car off as it might not start so drive it the mile or so home and turned it off. Left it a min then restarted it with no problems, car ran fine with no warning lights or flashing glow plug light. Then next day jumped in the car and went to set off but the car cut out. Started straight back up and idled fine, rev’d no problem. Set off and after about 500 yards the car cut out again, started back up and after about 200 yards cut out again. Started back up and turned around to get back home and cut out again but then would start back up with a misfire and cut out after a few seconds. Couldn’t get the car home so rang a mate who turned up with a snap on code reader which showed injector circuit A & B malfunction as well as injector 2 malfunction and injector 4 electrical fault. Tried unplugging the injectors one by one to try and get the car to run if it was a faulty injector that was preventing the car from running but it would only run for a few seconds then cut out. Recovered the car back home but by this point the car wouldn’t start at all. After various checks the fuel pressure seemed low at the fuel rail ( weak and bubbly ) and the car not showing any codes due to it not starting so replaced the fuel regulator on the drivers side ( the car has 1 on each side but a faulty regulator on the passenger side will still let the car run all be it badly) still wouldn’t even attempt to start. The car would just turn over and over. Removed the injectors and set them for testing which showed various faulty. Replaced all 6 injectors with new but the car still wouldn’t attempt to start. Removed the ECU and sent away for testing with a description of the fault the car was doing. The ECU testing showed it to be faulty but beyond repair. Bought a used replacement with the same numbers on a through a friend of a friend cloned the ecu to match mine. Plugged back into the car and it fired straight up no problems with no codes stored or warning lights. After speaking with an auto electrician he believes that either a faulty injector spiked the ecu or an ecu fault killed the injectors. Found loads of posts on forums with cars with the same fault but no answer to what the problem was. Hope this helps if anybody has or gets similar.

Thank you very much for the info I was a bit down hearted as I’ve never changed doors before and when I did nothing worked, but now I understand the situation am more upbeat just need a spline bit to remove the door actuators 👍🏴󠁧󠁢󠁳󠁣󠁴󠁿

No probs at all ☺️ and thank you ☺️

Markus Duesmann discusses Audi’s electrification, EV costs and viability of small cars Audi recently revealed its most affordable electric car yet, the Q4 E-tron, a mid-size SUV tipped to sell for between £40,000 and £50,000 when it arrives in UK showrooms late this year. It offers generous, Q5-matching interior dimensions in a more compact exterior package and is widely seen as the German brand’s first mainstream EV. Shortly afterwards, the wraps came off the A6 E-tron concept, a realistic glimpse at the electric version of the long-running A6 executive saloon. Clearly the electrification of Ingolstadt’s line-up is gathering pace, and there are questions over what that means for the brand’s ICE offerings, its small cars and its market positioning. Autocar recently spoke exclusively to Audi CEO Markus Duesmann for an understanding of what the near future holds for the company as it undergoes one of the most significant transformations in its 111-year history, ushering in no fewer than 20 all-new electric models by 2025. Could the Q4 E-tron become Audi’s best-selling car? “Hopefully it will. The car is certainly positioned in the middle of our strongest models, and we definitely want to do high volumes with it. Battery cars are becoming more and more significant in the market, and we’re finding that our BEV clients don’t want to go back [to ICE], so we expect strong growth. “Will the Q4 E-tron be the best-selling Audi? The truth is we don’t know. Deciding how much volume to install in our factories is one of the difficulties we have. We can react to changes, and that’s a good thing, but predicting demand was always difficult for cars with combustion engines, and this is harder.” The Q4 E-tron is as big inside as the Q5 yet more compact. Does this suggest that EVs will change the classic model range structure? “It’s a good question, and we’ve thought a lot about it, but we expect the line-up to stay much as it is now. In all segments, we have customers wondering when we’ll launch an EV that suits their preferences. You’re right to think that our EVs’ ratio of internal to external size is better, but buyers’ preferences depend on more than that: budget, whether you sit high or low, whether the car is short or long... So we expect the classic segments to stay.” The Q4 E-tron’s UK entry price is around £40,000. Will it be possible to buy a cheaper Audi EV, such as a Q3 E-tron? “We’re looking into this, and we do see some options, but we haven’t decided yet. Maybe we will do it, but not in the short term. The Volkswagen Group provides other opportunities for people who want smaller and lower-cost EVs. We think our market position means we shouldn’t stretch too much for lower entry segments.” Will electrification cut the number of Audis on offer? I wouldn’t expect the number of models we offer to rise, and perhaps it will fall a little. The number of combustion models will certainly fall as we launch electric models, but cutting the total number of models isn’t a priority for us. Keeping our stable together is the priority.” You’ve said Audi won’t develop any new engines, but Ford has gone further with the goal for all of its European cars to be EVs by 2030. Will Audi make a similar announcement? “No, my official announcement is that the last combustion cars we make will be the best of that type we ever make. It’s too early for us to announce a final date, given the disparate requirements of our many markets. But we’re in the process of reviewing the whole Audi strategy, and this will certainly be a discussion point for us.” Some manufacturers say the impending Euro 7 efficiency standards will add huge cost to engines, which, together with a fall in battery prices, will cause the cost of EVs and combustion cars to cross over. What’s your view on this? “It’s certainly true that meeting Euro 7 [standards] adds a lot of cost to combustion engines and that a crossover point is coming – we think by the middle of the decade at the latest. Euro 7 is a real headache, especially since it doesn’t do much to improve the environment. So we will reach this crossover point soon.” There are suggestions that BEVs have progressed so quickly that plug-in hybrids (PHEVs) might be needed only for a short time. Do you agree? “We see the PHEV as a convenient bridge technology, but it’s also a technical overkill, because it requires a car to have two powertrains – one of which will soon be an expensive Euro 7 combustion engine. And it still doesn’t make mobility CO2-neutral. That’s why we’re strongly focusing on BEVs for future Audi models.” Is this to say that you would prefer not to offer PHEVs? “No, we offer them now. The needs of our subsidiaries and our customers force us to do that. It probably sounds hard, saying it like that, but that’s how it is. We’re convinced that pure battery-electric vehicles are the future.” Are batteries truly reducing in price, and if so, how fast? Many things influence battery costs: commodity prices, materials supply, fluctuating demand, transportation... But the technology trend is that costs will go down, and significantly. We’ve predicted a 50% drop by the middle of the decade. The technology is already far enough developed to see that this can happen.” How will electric motors progress? “They will develop more too, especially when problems of battery range and [EV charging] infrastructure reduce. There’s not much sign of design convergence at present, but this will change over the next 15 years. The main drivers will be size – have you seen those tiny motors they use in Formula E? – plus weight, efficiency and cost. It’s not an easy technology. It looks easy and there are fewer legislative problems, but it’s still very difficult to do well.” Many manufacturers say that the existence of small cars is under threat, because they aren’t profitable. What’s the truth? “Earning money from little cars is definitely difficult. Diesels have already disappeared from little cars, because they’re just too expensive to make; cheaper to use, maybe, but expensive to make. We continue with the A1 Sportback [supermini], because it’s only two-and-ahalf years old. In the longer term, we will stay with cars in the A1 and Q2 [crossover] bracket. It’s not where we make money, but it’s a segment that our customers like, so we will continue.” So Audi will continue building the A1? “I don’t say that we will have a successor for the A1; that’s not so likely. But in the entry segment, we will definitely have an offer.” It has often been said that Audi is the Volkswagen Group’s biggest profit-earner. Is that still true? And if so, does that mean that you can do more of what you want? “Yes, it’s true that we’re one of the money-makers, along with Porsche. Our claim has always been ‘vorsprung durch technik’ [progress through technology], so we’re always aiming to emphasise Audi’s position as the spearhead of Volkswagen Group technology, and we will do more of that. “This is why I’m also responsible for engineering across the whole Volkswagen Group. In a position like this, it’s always helpful if you’re making some money.” https://www.autocar.co.uk/car-news/new-cars/how-audis-ceo-transforming-111-year-old-brand

Could you not transfer the wiring looms out of your old doors, along with door cards etc into your new doors?

You're welcome, you might be lucky and just dislodged the wiring. I believe the wiring runs inside the door, so you'll need to take the door card off to inspect the wiring condition.

Hi Steve, we have success at last. After changing that sensor car was ok for a bit then I got it remapped. However issue came back and the dpf was a common factor. So I've put dpf, egr and injector cleaner and car is now running great.

That seems a long time! Usually it's 3 months, but I know there's been an increased demand in cars now that restrictions be are lifting. Delivery time is also affected by the options selected. For example cars with special paint finishes, sunroofs etc take longer. Saying that it might take 3 months to build then a further month getting here thanks to covid and brexit etc.
