I'm going to be changing my glow plugs next week and getting my trusted local garage to do it (they've serviced the car since it was 3 years old). My A6 is the 2.5tdi V6 155bhp AYM engine. Mileage is currently 340,300 miles. I've asked them what manufacturer the glow plugs are and they said I have a choice between Bosh or NGK. price doesn't both me, I just want what's best. What do you guys think are best? Had a search online and on the c5 UK Facebook group with limited discussion on whats best. Just one guy saying bosh was best and is whats was fitted when new. Is that right? Also should I change the glow plug relay too for peace of mind? And if so is there any brand you'd recommend? Thanks for your advice 🙂

There you are 🙂 it's a handy thing to know. What did you find out about yours? What options were selected when new?

Please keep us posted 🙂

There should be a sticker In the wheel well listing the build info. In failing that is should be in the inside front cover of the service book. Once you have the codes you can use a vag options decoder.

Loads of documented cases. Audi are still working on a fix but do t seem to quick or bothered about sorting it.

I'd definitely start with a diagnostic check and then go from there.

You're most welcome.

After googling the fault code it suggests it's a faulty oxygen sensor: http://u1025.enginetroublecode.com/audi-a1 Here's a sensor for sale on eBay: https://www.ebay.co.uk/itm/143832354732?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=KUTl_YjoSSq&sssrc=2349624&ssuid=IE07kO4STZy&var=&widget_ver=artemis&media=COPY But the mechanic was right to say it could lead to a broken cat. Here's a reasonably priced one on eBay: https://www.ebay.co.uk/itm/265155282678?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=5zFN_KBLRBC&sssrc=2349624&ssuid=IE07kO4STZy&var=&widget_ver=artemis&media=COPY

It could just be a sensor, broken wire or failed module. I'd definitely recommend a diagnostic check to see what fault codes flag up.

The AC fault could just be a regas but worse case scenario it's the compressor. If it is then it could be an expensive bill.

I'd get the battery checked as a priority.

How old is the battery? Failing batteries can cause all sorts of weird electrical issues.

There should be a way to rest what you've done. It might be worth getting an auto electrican to take a look.

Wow, lovely colour and looks a nice example 🙂 guessing you're pleased with it 🙂

Now that's a stunner! I do love my British classics my grandparents had Vauxhall victors, ford Thames vans etc.

I'd be looking at a second hand one. You could place ads on breakeryard or breakerlink or on eBay. Alternatively you could look at a custom exhaust from companies like powerflow to see if they can supply one etc.

Bet you can't wait! Have you got it now? Vcds or obeleven are common ones.

Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂 I'd recommend a diagnostic check to see if any fault codes flag up. My advice would be to look at the MAF sensor, lambda sensor, fuel filter (incase it's clogged especially if the car has sat along time), spark plugs/HT leads, turbo (assuming it's the 1.8)

Well there is an issue which as you say is well documented. Currently there's no fix from Audi yet and it'll come out as a recall when they do have a fix. I'd leave the car with them until the car shows the fault.

No probs at all 🙂

Thank you for your input. Do you mind if I ask what club that is? At least it's not just out club then.

You breaking the car kev?

When your SatNav says: "branch left on trunk road"

I'd be contacting your local Audi dealer as it sounds like they're changing them under warranty.

I'd be trying eBay or placing ads on breakers sites like breakerlink or breakeryard.
