Td5 starting problems

[mendiplogs]

Easy cheap things to do are replace the fuel filter behind the drivers rear wheel as this gets binges up easily. When changed or even before you can prime the fuel system. Turn the ignition on and press the throttle down 6 times, you will then hear the pump priming the system. Once finished priming try starting her again.

You can unplug the air mass plug by the air filter and see how she starts then as if it's failing it will run better unplugged. Also on the inlet manifold there is a little plug with a sensor in the manifold. You can undo the two screws and it may be totally gummed up due to the egr.

If the ecu is defo oil free then hopefully one of the above will make a difference to the running to give you an idea of where to go next.

I do recommend getting her plugged in at a diagnostic garage and for £25 the comptuers cleared and go from there.

Hope this helps

HI TC a mate had the some thing it the fuel filter in the engine bay the copper washer was split so taking in air it took weeks to find it and the laptop did not pick it up all the best jon

Forgot to say how I resolved the problem....of all things it was the starter motor. Changed it and now she's as good as gold!!!

had diagnostics done today with no error readings, the garage thought it was starter but ended up playing with the crank shaft sensor and started working.........only for me to get home and start playing up again. decided to investigate ecu and have found oil, gave a quick clean to get excess off and started up better and repeated and started up nearly like normal. just hanging the loom to self clean, hopefully will have done it

Try the yellow ignition relays under the drivers seat if it still plays up. Sounds like you found the problem.

started up this morning, great news..........and died going round a roundabout doh! getting a modified loom fitted and tempted by a starter for good measure. i have been cursing it but still love her

Check the fuel inertia cut off switch under the bonnet. That and the relays under the drivers seat cause problems. I chased a similar problem on a customers recently,nothing shows up on diagnostics. Inertia switch is on the bulkhead next to brake servo,check it is full depressed and the plug on the bottom is secure. When you turn the ignition on, which lights come on on the dash?can you hear the fuel pump buzz?

[ben lightfoot]

its in the garage now so cant check these things, but will be glad to get the modified loom put in. all the lights are illuminated ie engine management, coil,oil pressure handbrake etc and the engine management and coil go out. I love it when its working but kind of missing my tdi right now

[Tyz05]

No probs,if all the the lamps are illuminating as you say it sounds like the relays are working fine. Electrics eh??!

[ben lightfoot]

ok so finally got the landy back and turns out it was worn copper washers on the injectors, so new o ring and copper washers and jobs a good un. managed to drive 13 miles with no problems so hopefully will still be good tomorrow
