Can anyone recommend a garage in the Aylesbury area conversant with the peculiarities of a Brazzer?

Been and struggling with running issues since I bought my 03 air cooled bus. Checked and re-checked the obvious things and now sick and tired of getting neck ache from crawling under it on the drive and don't fancy it in the current weather. Its been to a few local garages but they all assume it be the same as a conventional bay and are puzzled by all the sensors, ECU, lambda etc.

Really want to avoid having it recovered to Danbury or Brazilian campers as both are about a 200 miles round trip.


Cheers

Hi Purple
A lot of us on here use Paul Brand of Brand Auoto's in Hampshire.
He knows a lot about Brazi Bays and can doo virtually anything on them (in our opinion)
We would suggest it would be not too much of a stretch to try and use him
Hope you get your problems resolved soon

Thanks - I've already thought about them as I've seen several recommendations - but still a 75 mile recovery. I might give them a call to discuss it - what I want to avoid is the risk of getting it re-recovered if the faults can't be found/fixed.

Hello Tim

I bought the van in November 2016 - it ran well along a fast dual carriageway and I was pleasantly surprised how it pulled up hills and sat at 60mph over the 15 mile journey home.  Soon after it had a flat battery that had to be booster started and eventually had to come out of the van for a full recharge.  

I keep thinking back to what I might have done to alter a van that was running well - other than the flat battery problem, the first issue was straight after putting some standard 95RON unleaded in it, soon after which I pulled out of a junction and it hesitated badly and wouldn't throttle at all, leaving me stranded across a junction.

I initially thought it was bad fuel, then started to do the basic checks, looking for loose leads, dirty air filters etc. but from memory I did notice that the vac pipe from fuel pressure regulator was not attached, so I reconnected it and I also cleaned the distributor, the cap and rotor with WD40  

It went down hill from there.  

Changed plugs, leads, distributor cap and rotor, lambda sensor, tried numerous times to set tappets, which I know is the Achilles heal - but I would have expected it to run badly from day one.


The engine would start well without throttle, ticks over ok, and runs ok, but when out on the road it starts to hesitate within a half mile of running, the hesitation seems to be when needing heavy throttle - pulling out from roundabouts and pulling up hills.  Not really noticed at what point in the throttle action it starts, but I have noticed that if I lift off the throttle, the hesitation stops, the van picks up power and pulls away, but hesitates again as soon I try to apply more than a little throttle. Eventually the van wont pick up any speed and has to be pulled over.  Once cooled down the whole cycle starts again.

Ive checked and double checked vacuum pipes and connections, although seeing the small bore vac hoses without any hose clips seems odd to me as they are easy to pull off.

Ive had lots of help from Sparky Steve and bought a basic code reader and checked the fault codes again - initially none at cold, prior to start, and then after a run generally the same two codes 00561 and 00537 reappear. According to the fault code lists that came with the reader, 00561 is the Mixture adjustment control and 00537 is the Oxygen sensor control, but whenever you disconnect a sensor whilst doing any diagnostics you effectively introduce another fault code, so fault code reading can get misleading, even after clearing them.

Its currently hesitating/holding back after a few minutes running, probably not even getting to being warmed up now.  I think fuel consumption is poor and at one point in a 25 mile journey it would just about tick over, no pulling power whatsoever and left me effectively stranded.  Turns over and starts first time when tried cold the next day, but then reverts to hesitating etc.  Other than an occasional run up and down the driveway it hasn't been on the road since the MOT ran out in September.

It's only done 39k kms which matches up with the MOT history so I'm assuming its been laid up for a few years at some point.


I noticed someone mentioned recently about putting a straight edge across each bank with the rocker cover off to see if the three open valves are aligned – is this a basic way of identifying sticky valves?

Do you think when you initially disconnected the battery, that you accidentally touched the ecu with a spanner on the positive terminal? This sounds like potential ecu damage to me. Contact Paul Brand. He has my spare ecu. Maybe worth trying another unit to rule it out.

I'm an electrician by trade so always careful of shorting out terminals, and the battery was dead, so probably not that likely - but thanks for the offer.

I did contact a air-cooled race engine specialist who offered to take a look at the ECU, but he wanted the code that came with the van so that he could re-programme it if necessary. I have all the original documentation but no code is listed - was an ECU code supplied with new Brazzers?

I've had a suggestion of a possible sticky exhaust valve - I did note a slight leak of oil from one of the push rode tubes and another has been replaced at some point with one of the retro-fit sprung type.
