xpmoh Posted May 17, 2015 Report Posted May 17, 2015 Hello all, I have acceleration problem on my galaxy 05 ghia 1.9tdi while driving the car accelerates really slowly doesn't happen all the time notice when car is cold once heats up doesn't happen but when it does I keep switching car off and restart it then it drives OK again can happen 3 times in a row once car heat up doesn't happen again. I replaced egr valve with new one makes no difference I have ordered new map sensor as well thinking it could be that. I been checking for solutions on here came across ecu pipe in dash behide speedo clock but I can't find it there. Is there any other location it could be. Quote
