The car starts and runs ok, but engineering light on. I have found a garage who specialise in removing broken glow pugs without removing cylinder head. They say there are no guarantees that they can do it without removal but won't know for certain until they start. They can't remember when they last had to remove a head to do this job. Is it worth the risk?

the glow plug are used to heat the fuel on start up only, as a diesel uses compression instead of a spark (from the spark plug) have you try checking the connection on the glow plug, or changing the glow plugs themselves?
glow pug indicator and glow plug themself are 2 seperate system
test for power at the glow plug harness conector 1 each side over valve cover
test light clamp on batery neg test each wire going to relay for power on both side
then quick check on glow plug end test light clamp on positive test all wires
going to glow pug on each side f this does ligtht up the test light system should be o.k.
for the FICM i have used a hair blower on hi to warm the surface of if to start up a few of
these motors to get them back to the yard for replacment afterward
run a ffeet of these from 250 to 550 lots of problem and work 26 units
good luck
hi this could be a couple of thing, but sounds more like the heater relay is u/s, this is the one that heats the glow plugs before starting, check fuse box and see if fuse has blown first, but normally it would be the relay, the other thing could be a bad earth to the engine, check the earthing straps around the engine area, as one could be broken, also check the earth wire connection the heater rail to the plugs ( its the one that runs down the glow plugs and looks like a copper strip or similar ) check to see if is loose or broken...hope this helps please vote thanks
the most common cause of that prob with xtype diesel is the hose going to the intercooler splits and leaks or the jubilee clip on the intercooler has corroded and broken allowing the hose to blow off not easy to get to to repair
Not the easiest of jobs. Remove the engine cover. then remove the oil filter housing wich is the black plastic cylinder with the 32mm nut on top.
You should then see the glow plugs to the left and right of where the oil filter was situated. There is a plastic strip that clips onto the 3 glow pugs on either side of the engine. Remove that and you should then see the glow plugs remove and refit in reverse order
The problem is the glow plugs are bad or not coming on. Even though the "wait to start" light comes on, the glow plugs may not come on. I have found when this happens, the light comes on for only 1-2 seconds and goes off. With the engine cold, the light should stay on for about 5 to 7 seconds. The colder the engine, the longer the plugs should stay on. There is one glow plug for each cyl. The plugs are in the "V" of the engine and screwed into head. Only one wire goes to the glow plug and the wire runs from one plug to the next on each bank. You test them by removing them and grounding the body and putting 12v positive to the terminal. The tip should glow red hot like a cigarette lighter. There is a glow plug relay behind the air intake horn which also could be the problem and there is a engine temp sensor in the circuit also.
Yes, You Can do it. Normally Glow plugs located near the Injectors. But you have to use Rust off Liquid.(WD 40) Because, When you try to remove glow plug it can broken.If glow plug broken you have to dismental your engine Head.
Take off the glow plug power bar and check each glow plug with an ohm meter. Infinite resistance means it's burnt out. Check the three glow plugs on the right side of the head with your ohm meter as well.
Just removing and reinstalling the bar will fix any bad connections which might also have triggered the errorcode, so when none of the plugs seem broken, that might have been the case.
I had the same faultcode on my 2005 TDI some years ago; it ran perfectly, but after checking under the hood 1 of the plugs was indeed broken.
The garage should be able to test the glow plugs without removing them. All the need to do is use an ammeter or amp clamp and measure the current drawn by the glow plugs. the glow plugs should draw 16 - 20 amps each. much less than that and they want replacing.
