Engine rev limit warning and EPC error

**Simon134** · 18-01-2021, 05:08 PM

I have been getting random warnings on the dash for engine rev limit and EPC after i recently installed a new battery (AGM). The car has been driving normal whenever i got these warnings. Today for the first time the engine actually struggled to rev above 3-4rpm limit, like it was stuck in gear, and i did notice some power loss.

Has anyone experienced similar to this? Was it electronic or manifold issue for you?

I have the Mk7 2015 Golf R auto DSG.

Any replies are greatly appreciated.

Did you code the new battery in as you are supposed to , or just chuck it in and hope

Have a look to see what error codes have been recorded, that might point you towards where the cause of the problem is.

@Simon134: Hi. "Today for the first time the engine actually struggled to rev above3-4rpm limit"

? Shirley that can't be true? Is there a "K" missing -perhaps (or a factor of 100 - maybe)?

Yes, i got the mechanic who installed the AGM battery to re-scan and he supposedly updated the software? And he cleared all the errors.

Hi i got a EPC warning light today and pulled over after about 15 min of driving and restarted and revved a little and the light turned off . If i hold my foot down the car seems to only rev to around 4500 its some sort of rev limit when not in gear .

Normal behaviour for a modern VW.

Supposedly

Ask him if he recoded the battery as it isnt an upgrade of software

Its to stop idiots redlining/over revving it when not in gear
