Nice one. Glad you're working through it 😊 Cheers Steve

Hey Jez, I think it depends which gearbox is in your s4. You can find out by looking at the build sticker in your spare wheel well or the inside front cover of your service book. You can use the decider to find out: http://prsearch.planetvag.com From there you should be able to find out where the switch is Cheers Steve

Welcome to the forum Lynsey you'll find the members on here are a friendly and helpful bunch 🙂 The left circled button is to turn on/off the air conditioning. The right circled button is to allow the air to come through the dash vents. Cheers Steve

You're welcome, glad I could help 🙂 Cheers Steve

You're welcome 🙂 Wow you've got your hands full but ideal for lockdown 👍 Cheers Steve

Nice one 👍 Take care Steve

You're welcome 🙂 thank you, you too 👍

Hi Kev the siren/horn for the alarm is under the o/s side trim in the boot, also from my dodgey memory it has a back up battery which will make for the quite-ness. cheers Steve

Sounds like you've got a nicely maintained a4. There's no set mileage that the pump needs replacing, again I'd only do it once it fails. I'd do a battery test before changing it but thankfully it doesn't needing coding to the car. You might need to drive it a little but for the esp light and steering wheel angle sensor to reset themselves. The only problem you may have is the key might need recoding to the car after the battery change. Here's a video that'll help with reprograming: If the CD changer isn't in the glovebox then it'll either be built into the headunit or it'll be in the boot in the passenger side compartment. Regarding the rear seat I believe it might have been an option to ha e the split folding seats. My advice would be to have a look to see if there are release levers at the top of the seat backs where the headrests are and on the sides of the C pillars. Glad I can help 🙂 Once again, it's a very nice looking a4 👍 Cheers Steve

Welcome to the forum Stuart you'll find the members on here are a friendly and helpful bunch 🙂 Lovely looking a4 you have there. Such a great colour and looks good with the silver wing mirrors 👍 Cheers Steve

Welcome to the forum Stuart, you'll find the members on here are a friendly and helpful bunch. Did the car come with full/part service history? I ask as the history of the car may help in deciding what may/may not need doing. First thing I would be looking bat is when a full service was carried out along with then the cambelt and water pump was last changed. Injectors are a known weakness on this engine but I personally wouldn't change them untill they fail. Also it's worth checking turbo boost hoses, radiator hoses etc for any splits. You can get oil pump drive problems with this engine. The oil pump is driven off the balancer shaft unit by a hexagonal shaft (imagine a 6mm allen key with the 'bent' end cut off), which can wear smooth. This problem is quite rare though, and you dont have to expensively replace a substantial part of the engine to repair it. There are upgraded balancer what's available. Cost: "Only prob with going this route is weather to change the oil pump and sprocket at the same time, further cost of circa 300 quid for parts alone." Wing mirrors have probably been painted silver to give an rs4 look. You could changee the caps to blue but it's personal preference really. also if you're trying to find what options your came with when new there is a build sticker in the spare wheel well and in the inside front t page if the service book which gives all the codes. Here's a decoder to help you find what options your car has: http://prsearch.planetvag.com Hope I've helped 🙂 Cheers Steve

You're welcome, glad I could help 🙂 oh make sure you get the genuine Audi ones as there are a lot of inferior ones out there. It's what I've seen with other VAG cars with performance upgrades. Cheers Steve

The other area is the pollen filter housing. Mine cracked and was causing water ingress into the passenger side footwells. I've also had the scuttle panel one too. Think failed door seals can cause leaks as well if I'm not mistaken. Cheers Steve

You're welcome, glad I could help 🙂 Please let us know how you get on 🙂 Cheers Steve

Trek

Sorry I couldn't help more

It might not be the sensor buy the dog itself. What kind of mileage does the car do, ie city, motorway etc? Cheers Steve

Welcome to the forum, sorry for the late reply I've only just seen this. I wouldn't normally direct members to another forum but this link on audi-sport.net site might be useful: https://www.audi-sport.net/xf/threads/anti-shudder-valve-woes.291209/ Cheers Steve

Welcome to the forum Paul, you'll find the members on here are a friendly and helpful bunch 🙂 I've searched the internet and can't seem to find a manual on how to remove it. My advice would be to speak to an Audi specialist to ask them how you do it. Cheers Steve

Battle

Think they give a slighter stronger spark (5.5ohm compared to say 3.3ohm on a golf R) and allegedly more reliable, thus less susceptible to misfires than other VAG coilpacks but there's no other performance grains I don't believe. Cosmetically they're red so look cooler too lol 👍 Another good sparkplug you can upgrade to is NGK BKR7EIX. For your V8 I believe the Audi part number for the R8 V8 coilpacks are: 06E905115E Cheers Steve

You're welcome 👍 And I totally agree with Gareth. Don't fiddle with it untill your battery issue is sorted. I have a suspicion you could potentially Leave the car completely dead. Cheers Steve

Welcome to the forum Lee, you'll find the members on here are a friendly and helpful bunch 🙂 My advice would be to contact the companies who carried out the other modifications to see what they would recommend. I think on slot of performance Audi's NGK sparkplugs or Denso IKH27 or IKH24 sparkplugs are quite a common choice and on other performance VAG cars Audi R8 coilpacks have been used. Cheers Steve

Had a look online but not exactly sure on cost I'm afraid. Cheers Steve
