Hi guys,
It's been a long time coming, after a long while researching all my needs via your experienced and valuable posts, but I've come across something I need some advice on. I've had my S3 8L for around 18 months and am gently, progressively working on getting it up to scratch. I like to keep as close to OEM as possible, making enhancements where the benefits are obvious but without being noticeable. It's a Denim Blue 210 facelift with silver alcantara/black leather interior.
I've recently had a bunch of things sorted in relation to handling and balance... namely a new N/S rear trailing arm, rear shocks and bushes... with the aim of getting the car pointing straight and true at last. It's always had a habit of wanting to wander/push left at fast road/motorway speeds. I knew the alignment was out both ends after a couple of inspections at various places. Major toe out on front sorted by Micheldever Tyres, also identifying the rears to be massively toed in - well past recommended limits. The trailing arm has sorted that now. Soon to have all new tyres to replace those that have been scrubbed by the rubbish geometry... at the same time as a full four wheel setup. In the mean time it needs some re-alignment and care with paintwork...
Since the work was done the car's had an unexpected misfire around 5000 rpm. The OBDII diagnostics shows intermittent misfire error codes (not always visible) but it always seems to drive just fine otherwise. It's had a Stage 1 ECU remap (239bhp/255lb/ft) since I've had it but no other mods that I know of. All appears to be OE otherwise.
Also fitted Osram Xenarc Nightbreaker D2S bulbs, new headlight levelling sensors and had new clutch and other bits and bobs sorted.
Just wondering if anyone's experienced high RPM misfires and could point me in the right direction with some suggestions... and introducing myself and the S3 at the same time.
Thanks,
Tom
