VW Caddy 1.9 PD BJB 2005 - Long crank time #

Posted by Ken Hudson on June 18, 2013, 3:28 pm

Year of Manufacture *: 2005
Engine Size and Code *: 1.9 PD bjb code
( Optional) Fault Codes: no fault codes

hi we have a customer who complains of long crank time when engine hot. engine starts fine cold.
code read engine with no fault codes logged. customer has had vehicle from new and he reckons it has been like this from practically the start. dealer never found anything and was not really interested.
loath to get involved as we had a similat issue with a 1.9 PD golf and although we re-newed injector seals / loom etc, it only improved when we fitted a new battery, but even then it was still a bit slow to start when hot.
any ideas would be appreciated
regards

My suggestion on this is to evaluate fully the starter motor operation when hot, i.e. cranking speed and current draw and compare if possible with a known good example.

Have you checked for ECU updates? There was an update to resolve hot start issues.

Hi Ken. We have done quite a few poor Hot starting VW's and most of them have been caused by starter problems, In fact one of the first ones that we did was for our Local Main VW dealer who rang us to see if we thought that a slightly lazy starter would cause those symptoms, I said yes, So the sent the starter motor in and we stripped it, Cleaned it out and basically just lubricated the bearings etc ( may have even changed the bearings ) They refitted the starter motor and the fault was cured. That car had already been to another VW dealer and had already had almost every part replaced that they could think of without success.

Good Spec battery and starter motor overhaul would be a good place to start. P,S Don't send me the bill if it doesn't cure it.

I done few of them for hot start problem 1.9 and 2.0 on bosch system - by software modification

Theres a number of reasons for this issue on VW - the main ones being software to broaden the parameters of when fuel will be injected /engine start authorised & a modified starter motor from 1.7KW to 2.0KW along with an uprated battery in some instances.

Depending on what has already been done, depends on which avenue to head up next
