Title: Skoda 2.5v6 wheasel possible prob??
Post by: Crazycarzowner on 08 November 2013, 19:15:07
Dunno if its just me, but I think I 'may' have the beginnings of a problem with the Skoda??? The first start of the day (from cold) is now, as the climate is getting colder, takes a little longer. Usually you just flick the key and away you go. Now, its about 3-4 seconds more, with a puff of black smoke out the rear??? 2005 plate with 30k on the clock.

I thought maybe a heater plug maybe at fault, but according to the manual the MID will tell you if one goes down & register a fault? The little coil lights up when you turn the ignition on and you can hear the relay click once its done its job, so I think the relay is working correctly.
 It's a while since I've had a wheasel so I'm not fully up to date re. cold start faults, any ideas???

Try giving it a couple of goes on the glow plugs before starting.

Just because a relay energises, it doesn't automatically mean that it is working correctly. Use a meter to confirm that the glow plugs are getting a 12v feed when the relay is energised.

It is also possible that the glow plugs are getting weak, in which case a fault wouldn't register as the plug is still seen as being in circuit.

Hmmm, will have a look at the relay & plugs then, don't think its had any plugs since it was new. I bet its a fun job to get em out in one piece too  ::) ::) ::) I have heard horror stories of em breaking up in the head?

Had a similar problem with our Diesel Focus a couple of years ago. One really cold snap it starting taking longer to start and even cycling the glo-plugs didn't seem to do anything. ALL the plugs had failed - gone open circuit one at a time until no they had no effect at all! Changed them all and it started on the button again  :y

The system will detect faulty glow plugs but, there operated as pairs so you can get 50% failure before it shows. Also give the battery a good charge and see if it helps

When was the last time the fuel filter was changed.
Or when was it last serviced.

Last full , main service April this year. Gonna test the heater plugs, when I get chance  ::) ::) Like I say, it always starts, just takes a smidge longer, now its getting colder. I just prefer prevention rather than cure.  ;)

Apart from checking they have 12v going to them.....you can also check the resistance of them using a meter. IIRC they should read 3-4 ohms or thereabouts.......no reading or open circuit they're fubared and need changing  :y

They should come out easier with a hot engine  :y
