Staring engine when cold issue.

Thanks for the reply. I did some research prior to the 6 glow plugs that I replaced. Every forum that I reviewed explained that the Bosch plugs are not the correct replacement plugs and that the 5v Beru glow plugs are the correct replacement. I called the dealership and asked the service department what glow plugs they would use. They also stated Beru. Also, this problem existed prior to the new glow plugs being installed.

I have the same car and I also changed the glow plugs, I had one go bad so I change all like spark plugs. I found that both the Beru and the Bosch plugs were used, the only way you can tell which ones were used is to take one out and look. The Bosch have a higher voltage 11.5v while the Beru I seem to remember they were lower voltage 5v. The problem is that both will fit but if you don't have the Bosch system then you are told to use the Beru. Check out Beru part number 001 159 74 01 the Bosch number is 80036. Good luck
