Volvo V50 Reduced Engine Performance

I purchased a Volvo V50 estate (secondhand) just over a year ago. After a few months it started having problems when pulling away or when revving the engine over 3,000 RPM. This first started happening when it was really cold (-9’C)… however, after a while, the car would often go into reduced engine performance mode at any temperature if pushed hard. This was really dangerous because this would often happen when joining a busy road or when trying to get out of a tricky situation. The car would then stall or loose most of the power. I wish Volvo would allow me to override this setting on the car so that I could remain safe.

Having spoken to several mechanics and researched on the internet – the problem generally seems to be with the particulate filter. It can be either a faulty cable (next to the battery) or the tube to the particulate filter sensor becoming blocked.

Anyhow, I took the car to an independent Volvo garage near Banbury. They charged £60 per hr rather than £115 per hr that a main dealerships cost and the service was brilliant.

In my case, it turns out to be the tube to the particulate filter sensor becoming blocked. It seems that the Volvo dealer who serviced the car previously had not checked or topped up the EOYLS tank. This meant that the EGR (Exhaust Gas Recirculation) Valve that a pipe to the particulate sense and valve had become clogged up

The moral of this post is:

1) If I had taken the car to a garage when this problem first appear then it’s very lightly that the EGR valve would not become clogged and needed replacing.

2) Don’t take your car to an official Volvo main dealership because you can get better services at an independent.

3) Volvo know that this is a problem and should provide a sensor to the EOYLS tank.

4) Volvo should allow the driver to override the “Reduced Engine Performance” stalling and shutting down of the car. It is simple dangerous.

  1. I have the same symptoms in my volvo 1.6d. Everything you said there sounds reasonable, this fault is simply scandalous, I wonder how many people have died because of this. Volvo, shame on you.
