Sorry Pete just seen your email. Darkside charged me £555.59 inc vat to replace the injector seals. Seal kit + bolts/brackets was £108 + vat the rest was labour which took them around 5-6 hours. I had them service the car at the same time so my total spend was £852. (Apparently they were a sod to get out so glad I didn’t have time to do it myself).

Still shows as two broken play symbols on mine so just did two screen shots to show what it looked like.

I’ve seen it before where an oil leak in the middle of the V has filled and ran down both sides so would recommend looking there with a borascope or sticking a camera phone as best you can around in there for any sign of oil if yours doesn’t look like the pictures

Won’t let me upload a video of my failed injector seal for some reason

It’s unusual for all the injector seals to go at the same time on both banks and rather than it being oil it looks like a sludge of carbon that sprays under pressure on the manifold and inner wing. You’ll be able to here a faint ticking noise too coming from the injector. IMG_9185.mov

Wife drove the car today when the alternator not charging message displayed on the dashboard and the steering got heavy. Crank shaft pulley rubber dampener had sheared off throwing the auxiliary belt off. Quite easy to replace it’s held on with 8 multi spine bolts but needs a pry bar and a gentle work on both sides to get the old one off. You need a slightly bigger multi spline socket for the auxiliary belt tensioner to pull it back to get the bolt on and can all be done from above. Quite a common thing to happen so hope this helps somebody in the future. Quite pricey if you try getting one off the internet as euro car parts list it at £339 but if you ring them for a price with a trade account it’s £96.

Is the car turning over and not starting when hot or not turning over at all? If it’s turning over it’s more than likely going to be the crank shaft sensor. Mine did it a few years back and is quite a known thing on the mk1

It’s very common. There’s a green rubber seal that sits on the inner part of the pipe. You can buy it from Audi for about £10 and isn’t hard to swap just have a look at the pipe as you take it off as it has a seat that it needs to meet up to and give it a clean with a cloth before fitting the new seal and putting back together.

Car has now had all six injector seals replaced and a service with no problems reported. Work was done by Darkside Developments. Great service and very knowledgeable. Recommend to all

Drove the car the other day after my wife complained of an exhaust smell in the cabin when driving. Noticed a slight ticking noise from under the bonnet so upon investigation found one of the injector seals has gone resulting in a carbon sludge on the inner wing and exhaust manifold. Did some checking and the seals are sold separately at quite a cheap price. When changing it does also require a new injector bracket and bolt as the bolt is a stretch bolt and shouldn’t be reused. Unfortunately I’m so busy with some other bits going on for the min that I don’t have time to sort it myself, so it’s booked in at a garage to have all six seals replaced (if ones gone then logic would say the other five probably aren’t far behind it) and a service whilst it’s there. The seals and bolts are about £130 inc vat. I’ll post a couple of pics and a video incase anybody gets the same fault and wonders what it is. IMG_9185.mov

Probably a slight buckle in one of the wheels. Swap the front wheels with the rear wheels and see if it still does it.

Sorry I’m a bit unfamiliar with the obd code reader as I use vcds so not sure if it just reads codes or allows you to do measurement tests or not. But yeah the glow plug boots go very brittle and crack where the holder meets the plug and disintegrates when you pull them off. I had a problem with a previous Q7 where it through up a flashing glow plug light before dieing and not restarting so we changed the glow plug module (among many other things) but remember there were a few different types. Unfortunately this seems like one of those annoying faults that’s hard to diagnose and fix

Probably one of the led’s in the light cluster has/is failing and upsetting the canbus. Put the hazards on and check to see if one of the led’s is slightly dim or off.
