Sadly we’ve had a little bad luck with the golf at TSR for mapping.
Number 1 lambda sensor failure.
VVT not working properly either. They’ve said it could be a few things but have had to put together a quote with multiple solutions to get a “worst case” idea of pricing.
Could be quite simple as there being a bit of silicone or some other debris just blocking the oil gallery. Which would be best case.
The next thing to try is a well known working used VVT solenoid. Which isn’t too bad with pricing either.
Where it could be expensive is if they have to take the timing cover off, change the VVT pulley with the dreaded bolt that rounds and needs drilling out. TSR tell me they’re very good at getting them out in one piece.
The other thing they sorted for me was the power steering fault. There was no communication to the steering rack. Upon investigation the small plug on the rack had a bent pin. Quick adjustment to the pin and that sorted it.
They’ve also seen my rear wheel bearings have a lot of play - very confused as they’re brand new. Ordered a new pair for when it’s back.
So, all of this as a worst case price along with the mapping £1200 luckily I was sat down. Either way, it needs doing.

Cripes, not what you want when you’re so close...
Is it all sorted now?

yeah less than ideal.
Yes all sorted, had a test today to confirm.
“The seals inside the head had gone”
So luckily won’t be the worst case price. Back on the rollers today.

Well, it’s mapped. Complete different animal!
Very healthy numbers I think personally.

It’s certainly a decent peak HP figure. But what impresses me more is the delivery. To make peak bhp at almost redline is impressive and will certainly suit your track car.
Torque as well is nice and late rather than an early dump that tails off.
Looks like it’ll be a real weapon out on track.
