Feel like a right numpty now! Took the car out on a nice open strech of road and managed to replicate the noise a fair few times.
Turns out it's coming from the rear end! Its not related to boost as well, more when the car comes onto its power band and the rear pushes down if that makes sense...
I'm having a very strange situation where my Stage 1 tuned s3 makes a grinding/scraping noise when coming at full boost. It has a 3" DP and decat pipe.
Since owning the car I've done the following:
New DV
New Vac lines
New Forge DV and N75 hoses
Turbo reconditioned with brand new hot side and...
OK so now we are getting somewhere. First of all, Bill was right and it was a coilpack so that was sorted fairly easily. Also managed to borrow a nearly new MAF and the datalogs were showing 200g/s plus and peaked at 217 g/s with that one so it's making healthy power. I have ordered one from TPS...
No flashing MIL at all, have read it on other forums. Spark plugs are only 500miles old and are the ones recommended for mapped 1.8t's. Saying that I didn't gap them and they have been out a couple of times so will give do that tonight.
TRP Developments. Nikki at R-tech rates him very highly...
Another day, another problem.
Immediately after putting the car back together from the previous compression test I didnt start the car or move it. I did however fit a balljoint, track rod end and also a powerflex dogbone mount.
Took it out for a test drive and as soon as I hit 2000rpm and some...
Redid the compression test and got:
181ps 173psi 180psi 190psi
Slightly low on cylinder 2 but much more consistent and what is expect for the compression ratio of a BAM engine. So can hopefully don't have to worry about the block/head when going forwards in diagnosing this nightmare car.
Good...
Thank you very much for your feedback guys.
First of all only fault code present is:
17526/P1118/004376 - Oxygen (Lambda) Sensor Heating; B1 S2: Open Circuit
I told the mapper to code out the o2 sensor but the mil and fault code was still present. The car was logged quite a few times but with...
Cheers Bill, appreciate your help. You built my brother's LCR engine when he went hybrid, Imran from Birmingham but he works not far from you.
I've used that Polytek stuff on the gearbox and the engine mount to try and stop the movement. Hopefully that and the powerflex dogbone when installed...
Powerflex red Dogbone is in the post and should be with me today or tomorrow. I've tried adjusting the DP as much as possible and it must a cheapy chinese that the PO bought as I can't get it more than about 8mm from the prop. It seems on full boost it causes the flexy to compress and touch the...
As a very long shot I've noticed that in some cars upgraded engine mounts can cause knock sensors to act funny. Currently I have polytekd mounts and the prop is touching the exhaust on full boost and scraping. I was thinking maybe this was causing the engine to hear knock when it wasn't...
Worn rings is one of my worries, hopefully getting the new compression gauge today to re do the rest. Yep head was checked thoroughly and couldnt find any issues.
Seems we are in pretty much the same boat. Ive got no codes except the post cat lambda which is obviously missing. My brother...
Ok so from the beginning. I bought a 132k on the clock 2001 s3 about 6 weeks ago with a cracked manifold. New manifold was fitted a long with headgasket, cambelt, water pump and a full set of gaskets for the turbo and exhaust etc. I also fitted new vacuum hoses. Mods to the car are a full PCV...
Have just installed the very same kit on my BAM S3 and it went together perfectly with no issues. I bought it for the same reason as you, a full kit with good discount
Had a similar issue in my 2002 BAM, all of a sudden no starting and no noise from the starter. Holding the key in the start position for 3-10 seconds and suddenly it fire into life. Replaced the starter and all is well now. Funnily enough, I never had a problem with it starting it the...
