As shown in the videos, the drain grommet was blocked by debris, so it’s not a bad design creating a ‘water trap’ but rather very poor or zero maintenance in that the drain grommets are never cleaned out so just block over time. most cars have similar problems if the drains are never cleaned out. sunroof drains are a classic for blocking. Peugeot 405/406 were plagued by that. Curtain rod to ‘push thru’ every couple of months kept them clear. the old A6 C5 version had a drain under the battery tray, so it was a monthly job to lift the battery and flush it out. The sunroof would flood the passenger footwell if the drains blocked. It’s something that’s never mentioned in either owners manuals or service schedules. As an engineer I consider it a procedural failure on the manufacturers part to not be stating the need to check all the drains are clear at the annual inspection/service they all insist on. But it would be nice to know where they all are!

Hi folks, After advice on the Q7 E-Tron Diesel engine: I was chatting in the garage the other day about possible replacements for my current car (Mercedes estate) and mentioned I was looking at a Q7 E-Tron diesel/electric PHEV. They (the garage owner), said the engines were very unreliable, swirl vane issues amongst them. Have any Q7 E-Tron owners on here had any engine related problems? If so, what sort. cheers folks. Dave

Found a few bits buried in the garage - I have a new Audi rear wiper motor, bought for a 2004 A6 C5 but I know it fits multiple Audi’s, A3, A4 and A6 at least. Im after £20, as these are on sale for £35 up and up. I think £20 is very fair. Can check postage costs if needed, otherwise its available for collection from WsM (J21 - M5). cheers Dave

I have a used air suspension pump from a 2004 4.2 allroad that I Sold a while back.(tried tidying the garage and came across a few bits!). It needs the refurb kit fitting which would come with it. I just never got around to fitting it. Open to offers for it. As it’s quite heavy, it woul prob cost a fair bit to post, otherwise its available for collection from WsM (J21 - M5). if needed I can check postage cost. cheers Dave

It’s compulsory over there I think. Oct to March.

Just a thought but if this is your long term car, would a later engine go in? 2.7 or even a 3.0. The 2.7 replaced the 2.5 so might be fairly straight forward.

Just looked at a few online, onlinecarparts.co.uk have these pumps for £925, any garage should be able to tell how long/ how much to fit. But another £1000 seems seriously OTT.

Really sorry to hear that, that’s rotten. Is there a non franchised diesel or Audi specialist anywhere near you? I know Audi’s prices are ridiculous. My suspension pump went, Audi wanted £1500 to change it, quoting £1100 for the pump. I bought a new one from the manufacturer in the US for £300 and it took an hour in a garage to fit it. what. About a full recon engine?

Jon, did you get your suspension issue sorted?

Hmm, schoolboy error, sorry, just re-read yr post, sounds like an injector not working properly, enough that it doesn’t show as faulty but not well enough to squirt enough petrol. Possibly more than one injector? petrol can gum up injectors over time, which really messes up the spray and droplet patterns ( big drops don’t burn as well as small ones - less total surface area) and amount of fuel let thru on each injector cycle. Hope this all helps but please Keep us updated won’t you. Cheers Dave

I ran an allroad V8 on lpg, used to ‘lean mixture’ and ‘misfire’ faults coming up fairly randomly, eventually worked out that these would show up after shorter runs where the engine didn’t reach full temp but it was warm enough to switch to lpg. Seems until the engine is at full normal temp, it can cause this sort of problem, especially if I floored it to overtake, seems the lpg and cooler engine caused a slight misfire which then triggers the fault codes. letting the engine get fully warm and using a very, very slight slowing of throttle movement ( ie; no stamping on the throttle to get it to kick down earlier) stopped it. More of a driving style and limitation of the lpg fuel. (It’s much higher octane than petrol, so ideally you need to advance the timing a lot for best lpg efficiency but most engine ecu’s can’t accomodate that, nor can most lpg ecu’s. Im assuming that it only does it when you run it on petrol and lpg, ie; it’s fine on just petrol? Dave

The high pressure wash could force water past the connector seals and into the electrical connections on the cable and sensor. I’d want to disconnect each one and make sure it’s bone dry inside both the plug and socket, check there’s no sign of any residue, corrosion etc on the pins and socket at the same time. id wash the contact cleaner off sharpish too. They can leave a residue on plastics (cables, connectors, sensor case etc) that holds dirt and eventually damages the cable insulation. (Same with stuff like wd40).

I had a 2004 allroad running 18” wheels so bought a cheap set of 17” twin spokes for winter tyres (17s are a LOT cheaper) and used continental winter contact, saves on having to swap tyres and rebalance too. Pretty much unstoppable! Do miss that car! i generally use mytyres.co.uk to compare the specs of different tyres. think I’d defo go for smaller rims than 19” though. Not even sure you can get 45 profile winter tyres at 19”. Hmm. Hope this helps Dave

I’ve got a set four 17” Twin spoke alloys I need to get rid of as I want the space in the garage to do the canoe repairs I’ve taken on. They are in reasonable condition, ET25, pcd 5x112, 7.5j. One wheel has a small dent in the rim but it didn’t affect the tyre and was only noticed when I transferred the winter tyres off of these wheels. Ive got them on an eBay auction at £25 but I’m open to offers just to get the space. Please call me on 07941 721168 if you have any questions. the Wheels are a bit buried at the moment but there are phots on eBay. Listed under ‘Audi Allroad Twin Spoke Ally's. (& I’m having trouble downloading the photos from the cloud!) Cheers Dave F
