Tdi Stalls / Loss Of Power

[rustychain]

Hi there

 

My Galaxy 115 Tdi has developed the following symptoms:

 

1. Sometimes after starting from cold, the engine dies whilst it's idling (approx 30 seconds after starting, before setting off)

 

2. The engine also intermittently loses power. For example, the other day I was driving along a dual carriageway, when the engine lost power (ie the engine was still running, but the engine didn't respond to pressing the accelerator). This lasted for a couple of seconds or so, but seemed like forever!

 

Any suggestions on where to start looking please?

 

Thanks

 

Sean

Hi there

 

Intank fuel pump or relay maybe!!

check that your blades are not coked up in your turbo common fault on diesels

(1) Check glow plugs are working.

 

(2) Remove Vacuum tube from EGR valve cover both open ends with tape to avoid ingress of dirt etc.

 

My idle problem went away with (2)

 

You can do (2) first but I suspect that failed Glow plug introduces soot into the system which may cause failure of the valve which controls Vacuum applied to the EGR valve, causing it to stick open.

 

The extra soot also seems to cause sticky turbo vanes (overboost effect)which can be cleared by some high revs.

 

Since I changed my Glow Plugs the Limp Home mode caused by Overboost has gone away.

 

After driving over 2000 miles with (2) set up and a caravan attached, I suffered an overheating problem which I am still investigating though car still is driveable. It may not be related.

Thanks for the responses! Gives me a starting point.

 

How do I check if the blades are coked up, do I have to take the turbo out??? :unsure:
