ESP cuts in unexpectedly?
Had vmax day today and after a decent first run had the car struggle coming out of a right hand corner. Weird thing is in the corner I would be going 60mph well within the limits of traction on a trailing throttle, and when straight and applying power the car would just be completely dead for a few seconds , catch again briefly, die briefly again and then finally resume.
There is no indication of a loss of traction / slipping / sliding although the car is under a very heavy lateral g just before this happens.
Something I just thought of could it be fuel starvation issue ? Where is the fuel pickup in the tank ?
Any other ideas ?
I'll let PLopes talk about his beast ... 168 pulley and he smoked all the 55's today !!!

OK he is too modest to say but he clocked 191 through the traps and that was late in the day after he ran out of ice ... unreal and earlier 188.2 on a pbox into a proper headwind... 
Car is a freak with a Kleeman 168 pulley, headers, shelf tune, no cams, Renntech TB and airbox, TTM scoops, rear tank.
He is da man!
I managed 185.0 on my first run and did not break 180 after that ...

Hmm dont think its IC pump otherwise it would have tripped again closer to the beams. It ran solid after it eventually got going again....
The next run I thought I would try with ESP off ... err never again as Paul will testify, car one way then the other almost ending in a proper mess, fortunately before I got to the long corner and straight. It was after this episode car went limp on me though mbe it was still in shock!!!!
Who knows. Felt like a fuel starvation, or a loose sensor tripping esp, did not feel like the blower switching off felt more like no ignition or no fuel...

Also check your fuel pump, injector rail and injectors. The crankshaft sensor must be checked. It somehow sounds like the infamous IC Pump, but you say it's not.
I hope you find the problem.

These are going to sound like odds questions......Is your steering wheel straight when driving is a straight line? Have you had a wheel alignment lately? Does the same this happen with a similar corner in the opposite direction?
If the steering angle sensor isn't centered then the traction control can activate what appears to be "early" in either a left or right turn (it'll only be in 1 direction, and most times high speed corners). This is usually because someone has removed the steering wheel and put it back on off-center and then the vehicle has been realigned to suit the new steering wheel position.

Hmm that could be it ... although it did not do it the first time but I was more sedate on the corner on the first time this also unfortunately supporting the fuel starve theory though. Also the esp seemed to intervene after I came out the corner (in the corner I was on a mild throttle) and was almost 100% dead straight which is what really confused me.
The wheel was one notch off centre recently and realigned by my MB tech at the recent service, I dont think a one notch misalign will cause this though? But there has been allot of fiddling with the sensor and the steering wheel so perhaps I get lucky and this is it.
I have not been abel to try is on a corner in the other direction but will try find one! car in bits though so its going to have to wait.....

It can be a simple as 1 tooth out on the column. These cars dont suffer fuel starvation in corners unless fuel is low enough that you've only got about 1km to go until you run out.
If you can get access to SDS then you can check the steering agle when the steering wheel is centered, anything more than +/- 5deg is going to give you a issue but as long as it's less than +/- 25deg probably wont trip a fault code

When you say one tooth out you mean on the connection between the steering rack and the steering column?
So I would just need to reset the centering via Star or the battery reset method..and don't have to align the steering column tooth to the steering, or do they need to go back together in a specific alignment ?
