Egr/throttle problem

Steve001 · Apr 24th, 2016, 13:35

Hi, I'm a bit of a novice but I recently bought an 09 Volvo v50, 2l diesel. I constantly had a jerking motion when accelerating. The dealer struggled to find the problem. I had a power system fail and put in a new battery and alternator. The jerking continued so I brought it back to the dealer who told me they fixed the EGR. The jerking returned and the engine system service light came so I brought it to s Volvo specialist. They found that the EGR had been blocked with a blanking plate and the vacuum hose to the throttle had been blocked with a bung.

The garage replaced the EGR and the car failed to start. They thought the prob was the flap in the throttle. They sanded the flap down and the car now starts... But is a bit touch and go. The jerking is back as bad as ever.

Any ideas what the problem is. If I replaced the throttle would that solve the start/jerking problem? I'm at my wits end with this car!!
