Hey all, this ones got me stumped. I've got a seat inca van, 1.9 na diesel. Same as a mk2 caddy and it's got an intermitant starting fault in that sometimes (now most of the time) it won't turn over. Turn the key and nothing, dash lights yes but nothing else, no clicking, nowt  Now first thought was starter relay, but, erm, I can't find it! I've tried pulling every relay, one by one, out of the fuse box under the dash and it'll still turn over  ( this was when it wasn't so bad so would start most of the time) Now things I've tried and noticed, if I rocked it back and forth while in gear, it would then normally start on the key (this no longer works), If I gave the fuse box under the dash and thump it would normally start, even though, as far as I can tell it has nothing to do with the starting circuit . If I try and bump the car off and get a couple of turns on the engine with the clutch dump, it would then turn over on the key! But only for a second or two, then nothing, give another bump and get another few seconds on key ect. Whacking the starter motor doesn't work. Shorting the starter with a screwdriver gets the starter spinning but doesn't throw the solenoid. (could this be the problem ) Also, can't find the starter relay under the bonnet Or anywhere else *HELP*  I'm using my Merc as my daily and I can't send it to get sprayed until I've got the inca working. Cheers in advance for any help of pee taking at my useless-ness. Dave |

I'll get back to you as to where the starter relay may be as I have a VAG group parts database to hand.
edit to add what year is it and is it the seat or vw version/

Have a screen dump from ETOS of the Relay locations list. If you want part numbers for the solonoid give us a shout as I have them. Paul   |

I fixed an identical problem with an octavia diesel (SDI engine) a while back... it was a dry joint inside the engine control relay. Said relay was behind the instrument binnacle, and it took longer to find it than it did to fix  |

Has yours got a number 109 replay? Its common for these to play up and cause intermitant starting faults until they eventually breakdown altogether. Their so common alot of people carry a spare. don't bother with second hand as there only £10 or £12 from the dealers

#bl1300, cheers man, it's a 97 seat inca. The lists you've posted, tbh, I'm not sure what I'm ment to be looking at Sorry. Part numbers are handy tho if I can work out what I need. #westy, I'd not heard that, cheers. I'll try hot-wiring it, seems it's only ever vdubs I end up having to hot-wire lol. #SOC, behind the clocks you say! I'll have a check there in the morn  #superbean, as far as I know it's got a 109, I've done some searching about online and found out the 109 is a common failure, but couldn't find it's location online or on the actual car! Anyone have any idea where it is? Cheers guys, keep the ideas coming. |

When you know what you need give us a shout and I should be able to find the part number the software ive got works for all VAG cars from 96 onwards by the way.
To explain the list.
relay A
relay location/code number 3/30
That means relay A is labled number 3 in the main box. Basicly it tells you what each relay does and where it is in the box plus giving you the VAG part no

The 109 should be in the fuse box inside the van under the dash on the drivers side. If you've got the small glove box open it and remove it. Iirc the relays are across the top of the fuse box. Sometimes tapping the relay while trying to start works but it does depend how badly it's broken down.

Cheers guys, glovebox is already out, squeaky blower fan, and I didn't notice any relays but I'll double check. And no relays marked 109 under the steering wheel, I've removed each relay from below/right of the steering column and the van still turned over, surely if one of those was the starter relay it would have disabled the starter motor when it was removed?!? |

Its not the 109 fuel pump relay. When this fails the engine spins over but doesnt start.
What is a common problem on those 9k vans is the main power lead that goes from the live terminal on the battery to the starter and alternator corrodes and doesnt carry enough power to spin the starter.
You also need to check to see if you have a cranking live to the starter solonoid. If you don't then its the electrical part of the ign switch. These are about £12 from vw or cheaper from GSF

Awesome, cheers man! I think power supply to the starter is ok as when I short it with a big screwdriver it spins up good and fast! But the solenoid doesn't engage the ring gear.
I'll try all of the above after I've had a bit of a sleep, just finished a nightshift and I'm pooped!

Don't say that! Well if it turns out like that I'll just fit a starter button, hidden |

The switch is normally just held in with one small screw at the back but it can be tricky sometimes getting to it.
