revs climb on gear change cruise control doesnt work
« on: October 15, 2018, 07:44:49 PM »
evening
noticed the other day when driving that the revs climb about 700rpm on the gear change , had the car scanned and it came back with clutch switch so I ordered 1 from vw and fitted it and its still the same , also a facebook post mentioned to check my cruise control and hey ho that's not working either , I don't know if they are both connected to the same fault
any help please
cheers

Had the same with the same symptoms on mine.....but since I had to rewire the ecu on mine it wont be your problem.
But.......it was the clutxh sensor wire I had on the wrong pin and after moving it it all worked fine.



So......yes it will be your clutch switch or the wire going to the ecu.

I’ve read about this before, check wires going from clutch switch (which is part of the clutch master cylinder - behind heat pouch) and if all seems good, go for a new clutch master cylinder. On euro car parts they don’t come up under a GTI reg, but I’m sure the product number you need is - 136440300 double check with the guy over the phone then go back on the site and use there discount code. Or the guy might give you discount over the phone. Orrrr go on eBay I think Sachs
Do one for less than £40. But I would say more than likely it’s your clutch switch causing the issue.

checked the wires as far back as I could and all worked, checked them at the stork end just in case and they were find , still couldn't figure it out so was at a loss as it had been like this for 3 or 4 weeks, doubled checked the fuses and 1 was blown , new 1 in and bam , car was fixed
I hate cars
