First time on track with the CSL

[Jaw_F430]

:supz: Took the car to Bedford Autodrome yesterday. Didn't plan on going on track as I was going with a few mates to watch them on track, but ended up taking part. I cannot believe how good the car is on track, I didn't even have cups on and the mechanical grip is unreal:thumbs:.

I did a few laps with an instructor sat next to me which made me realise how much faster I could go :drool:. I then let the instructor do a couple of laps with me in the passenger seat. It was good to see what the car can do in the hands of a instructor/race driver:thumbs:

There was two other CSL's there, don't think they are on the forum though. One of them was running full slicks:thumbs:


I think I need to get some CSL cup brakes though as after about 2-3 laps the brakes were fading:banghead:


I must of been running on fresh air when I left the track as the trip was showing ----. Filled up at the garage just down the road and managed to get all on 64 litres in the tank!!!! Always thought the tank held around 60 litres



The car was great all day until the last few laps I got the drivelogic light on the dash (see pic below). The handbook tells you there is a fault on the drivelogic system but does not tell you what the problem is. When I come back into the pits and left the car cool down for a bit the light didn't come back on when I restarted. Anyone else had this light come on? If so what was the problem?

SMG fault, it can be from trackwork. Worry if it comes on and stays on...

[Mark CSL]

I get that all the time
I also get the ABS turning off if i brake hard but i think it is the BBK thats fooling the ABS :whistle:

my cog lit up last year and 2 months later the gears started slipping 3 to 4 and needed new gearbox, but that could have been coincidence:bigcry:

I am on my second gear box :bigcry:

Funny you should say that as before I went to Bedford I noticed an unusual change going into and from 3rd!!

I have had a new (well second hand with 7,000 miles on it) gearbox for this very problem, but it didn't solve it. I'm going back in tomorrow to get the hydraulics changed, supposedly the rod that actually changes gear can become worn and we're hoping that's the problem.

What sort of experience are you getting from the 3rd gear change?

ewe, that sounds scarily expensive. Here's hoping it's not.

Bloody hell :bigcry:, is that clutch slur? or is that less subtle than that?

[benCSL]

Exactly the same problem for me (the 4th gear)...after lot of work...-new gearbox- and lot of euros; bmw says that the car was so old : 70% in warranty on the gearbox.
My car was 44000km... bad problem for this kilometer....
I am not alone i think it's a gearbox default....:banghead:

mine was slipping some gear changes 3 to 4 (not going inot gear)

Murketts checked the GBox and found traces of metal in the oil which is hte synchro destroying inself so got aBMw good will new gearbox:thumbs:

got a vid of it soemwhere as i took it to Murketts to prove it as it was very early in the process but had vid from track days;)

That would make sense. Listening to that vid, the car seems to attempt the change, doesn't get it, tries again (or the gear is attempted again) and eventually it grabs. I expect the gearbox expects the synchro to work in a predetermined time and wouldn't do like a human does and slow a gear change if it's being notchy etc....

I wonder if the change speed was changed to a slower speed if it occurred less?

Yep, eeeeek! Glad mine doesn't do that!

Well, if you were on standard brake fluid you can't expect it to last long to be fair!

If only you had some CSLRegister.com cards to hand out........;)

[bryce]

Steve's video sounds similar to what mine is doing (except I dont rev so hard :hahaha: / :gayfight:). Not had a chance to get it checked out again yet.

Any suggestions of what I should fire at them? *apart from a spud gun
