Had my car mapped by the guys at Evolve today. The problem is I'm already getting, I presume, clutch slip?
Car is on 85,000miles and is mapped to 304bhp and 500ft lb. In higher gears the rev needle occasionly spins up round the dial, then drops and bites again.

I probably shouldn't be surprised and it probably needed changing soon anyway.

Iv searched but I'm still not sure how best to fix this? OEM or something beefier? Or live with it and drive round it?!

You'll need something uprated, new standard clutch wouldn't stand up to it for long. Excellent figures though!

It will give up completely eventually, so take it easy for now until you get a replacement. I had a sachs organic clutch on my Ibiza Cupra TDI, held up to the torque well. Not sure what's available for the 330D though.

There's a reason why the 335D didn't come as a manual

Thanks for that. Was it much more expensive than fitting OEM?

[ChrisBoom]

It was around £200 more, well worth it though. I had it for 30k after fitting and it never slipped once.

[E92Dan]

I spoke to "MR CLUTCH" who quoted £260 labour to fit a new clutch and DMF. It's looking like a big bill to do both.

[ChrisBoom]

Ideally you could do with a conversion to a single mass flywheel, DMF's are prone to failure.

Nice figures, shame about the clutch, is it worth talking to Evolve? They may tone it down a tad for you!

The car was 239bhp as standard so the gains were very impressive. Evolve have said they can map it to 280bhp and 430lb ft of torque. I'm not sure how a standard clutch will cope with that? If it still slips I will probably revert back to standard as I don't want to fit a performance clutch and new dmf

... and the vibration from the engine will destroy the gearbox. That's what DMFs are there to prevent. Would you rather the DMF fail or the gearbox?

This is why I am wondering if an OEM set up can cope with 280bhp and 430lb ft of torque

I'm sure I've read on here that the manual box has a much lower torque rating than the auto. Not sure of the exact figures, but 430lb ft is same as 335d so I'd be inclined to say that it is still too high...

[phil200tdi]

If its the same box as the 335i then the limiting factor is the clutch not the box.

With an uprated clutch the manual will be much stronger than the auto. Guys with big single turbos are pushing 750hp and 600 TQ.

Mine is at 510lb/ft tq - I now have a Spec clutch to hold it!.

[E92Dan]

Wow that's some big power!

[MEGA]

Sorry but I don't understand why they mapped it so aggressively if the clutch was slipping? I fail to believe that a car so obviously slipping wouldn't have noticable slip before the map was applied?

I'd have refused to map the car in their shoes or made it very clear to you about the clutch before mapping it.

Didn't they test the car before just flashing it???

Good numbers though. Post up the RR. I like such things. Just a shame the clutch bill is going to bite.

I've been in your shoes with my 320d, had to pay circa £1k all in for the job. Hope you can get it cheaper!

[E92Dan]

I had no clutch slip before the map. They did a rolling road test before they updated the map. I was told it could get some slip if it's an older clutch and its on its way out.
I've just had a quote for an OEM clutch and def to be fitted......£ 1100! Ouch. Not sure how that differs with performance parts though.
I will try and get the RR up later

I had Avery similar issue admittedly not a bmw it was on a mk4 golf tdi with 130 Diesel engine, the car drove fine no clutch slip at all. Had a remap to 170bhp and it started slipping at low rev with the high torque! I opted for a standard clutch again, the car was on 116k. Fitted a new clutch and it was fine, I didn't change the DMF either.

I can only say that maybe the pressure plate had become weak over its many operations and temperatures it sees! But from that day the clutch has been fine and its now on 148k and I gets some abuse when I drive.

[markymark34]

ive had 3 330ds remapped. Big miles = clutch slip if you go too far and probably unnecessary stress on other components. Im wondering why you went so agressive with the remap? all my maps were about 280-285bhp and i think 420 -440lb/ft (honestly cant remember the exact torque figure) . No clutch slip even on a car with 92k.
The car was a flying machine, really no need to push things any further.

Im assuming we are talking 231bhp engine?

[phil200tdi]

Producing so much more torque will make a clutch slip.. Most tuners will make you aware of this before mapping the car.

Reverting to standard will likely fix the problem if you had no slip originally.

Pay to play.

[jquan1]

I got the same issue with mine, its mapped to 286bhp from 231bhp and I get a slip when in 4th under full power, sometimes. Its got 60k miles now, I just don't thrash it so much.

[E92Dan]

Thanks for the advice guys.
I wasn't aware of a lower powered map by Evolve. My clutch was always my concern with a remap. I'm going to change it for a new OEM one and get the car remaped on the lower power setting. This car is my daily driver and must be reliable. My previous two cars that I didn't mod did keep giving me problems, so I don't want that again. I think 280bhp and 430lb ft will be plenty for me as I only wanted a bit more oomph

[E92Dan]

How does £550 for a LUK clutch,labour and VAT sound to you guys? It's a local garage so is convenient
