The customer tells me that the battery has not been changed recently, but I'm not sure that the car left the factory with a Bosch S3 on it. Either way, if there is any doubt in the matter, the battery is going to be changed, and probably I'll seek out the best that will fit in the tray. I'm not a big fan of these Bosch batteries (whether they're OEM or not), and I've seen too many "conventional" cars have trouble on cold mornings with them, let alone a design that seems as sensitive as this Golf. If anyone has direct experience of other makes on this sort of application, I would be much appreciative of advice. My personal preference would have been to go to Varta (OEM to so many Landrover products) or Yuasa (never had any trouble with these). Bosch batteries are made by Varta. A Bosch battery is literally just a Varta battery with a Bosch label stuck on it, exactly the same spec.

There's 3 parking spaces at my local asda that seem to generate lots of non starts. Rolling the car backwards a few feet gets most of them running. I didn't believe it when I went out to my 1st job there, and was told to push the car out the space before trying anything else. Does the punter always park in the same place when it has the problem? Can't see it being likely though. Does this one have an earth under the battery tray like the mk4 and 5 did? Seen a fee with that earth broken which will cause starting problems. Or the fuse box by the battery as already mentioned Hey Nate When I was on a course in the nineties the tutor told me about a section of motorway in Nuneaton Nearby there are transmitters for BBC world service Aparantly there are permanently parked recovery vehicles there that tow conked out cars two miles further and it's ok again! The other thing he said was that model of micra would stop running if you held a mobile under the bonnet and someone rang it!!!!

That's the beauty of being your own boss, you haven't got a electrically ignorant service manager wondering why it's taken so long, just make sure the phones turned off and workshop doors are closed

Varta and Bosch are both owned by Johnson Controls, so are pretty much the same.

Johnson controls manufacture the ford oe batterys Johnson Controls provides instrument panels floor consoles door panels overhead systems and overhead consoles. When I was at JLR a lot of the above goes into the Evogue and Freelanders.

Varta and Bosch are both owned by Johnson Controls, so are pretty much the same. Hmmm, that's a strange thing then. They should perform exactly the same. Maybe all I'm seeing is a bad batch of Bosch batteries, from one source or another. Chances are, they've been left sitting on the shelf for a while. I tried to have a look at the date-stamp on the Bosch S3 unit on the Golf last night, but couldn't see one on any of the visible faces. I reckon I'll have to take the battery back off the car to find-out. I need to look at the data from yesterday's test a bit more closely. I left the laptop in the workshop, so couldn't do the calculation on the internal resistance, etc. last night. It's going to be a close call, it just seems like a 500A (EN) CCA rating is marginal for the set-up in this car, so maybe I need to see if I can uprate the battery a bit. What my current clamp is telling me is that the first churn of the engine is pulling approximately 580A at the starter +ve lead, so I'm left with that question, "Did VW spec the battery deliberately wrong, or did the starter motor suddenly get a whole lot bigger and meatier, or has someone (most likely) had a nice big supply of Bosch batteries that they needed to shift before they all went completely flat, not particularly caring to confirm that it was OK for the car?" If the diesel Golf VI has the same battery tray, I reckon I could just go down that route and be done with it. In any case, fixing the battery is going to be cheaper for the customer than fixing whatever it is that's marginal now. If the battery doesn't have a Bosch label, I stand a chance of not getting Del Boy's stock!!

When I was at JLR a lot of the above goes into the Evogue and Freelanders. Indeed, a lot of JC went into the RangeRover, Disco3 and RRS seating systems as well (the whole armchair!). When you get down to the gritty, there aren't that many suppliers out there, and the market is permanently in a state of flux.

Yes its all very scientific, do you do lots of experiments ? Only by accident. I ought to do more to build-up a set of reference waveforms, etc. but there never seems enough time in the day to do the job professionally...

Val, you mentioned at the beginning that you fitted a replacement starter, and were then subsequently caught out by the engine fitted in the car not being the one you originally believed it to be. So, have you actually fitted the correct starter / solenoid..?
