Power Loss/poor Running Bus

[scrote]

Hi everyone - have been in and out of the forum as a guest and found it very usefull - currently at the end of my tether so joined for some advice or if not at least a sympathetic ear - sorry about the user name its a nik name from work thats stuck !!

 

this could be long winded so grab a glass of something if you intend to read the lot !!

 

TDi 115 bhp 02 - 87k - some history but essentially was a company motor serviced in house

 

family needs meant i was unable to purchase a car at my usual

[mumof4]

Bus???...its not a bus!!..it is a highly designed mechanical piece of engineering that is pure genius simply because of the amount of faults it has!! :)

 

 

Anyway..welcome to the forum. ;) ;)

Hi had same problem with my sharran 1.9 tdi turned out to be E C U and rather expensive.

Thanks for reply - I appreciate all comments - I dont want to get fobbed off by the "experts" at the garage and end up changing a whole load of stuff that isnt needed !!

sticky egr valve could cause the intermittent nature of the problem.

 

While not the source of your problem there is a school of thought on the forum that the MAF should be treated as a service part to be changed at 50-60k - thick film sensor tends to degrade over time and so disconnecting makes a big difference but replacing it will also make a big difference ;)

Thanks - ill see what the "experts" say next week, although i have to say i have little confidence in them. To keep some service history record I had the Bus serviced by a local garage who over-filled it with oil - I dont need to pay anyone to do that - i am quite capable of wrecking my own engine- at a third of the cost !!

 

I have made enquiries at both Ford and VW garages re prices of MAFs and for the same unit Ford wanted a couple of quid short of

If you have a buddy with the same car try a tempory swap of the MAF, then the T-MAP - and both you try it.

 

Only try one at a time. this is easily and quickly done if you get a tamper proof torx driver set (for the MAF) and just change the part that holds the plug.

Thanks for that - I know which bit is the MAF - which bit is the T-MAP and what is its purpose in life ?

[Dave-G]

The T-Map is just under the other side of the engine cover, with a similar looking plug on it. It's a manifold temperature sensor and only needs a cross head screwdriver to remove it. Shown in photo

[scrote]

Thanks for that - i did remove the T-MAP last night and it was covered in wet oil which i beleive has run down from the EGR valve(see my first post) and i dont think a wipe with a rag will cure it ??

The problem i have now is

1 - is it a faliure of either the MAF or the T-MAP that has caused the oil from the EGR

2 - is it another problem that has caused the oil from the EGR which has made the T-MAP fail ?

3 - This is looking expensive - do I sell my twin boys or re-mortgage the house

 

Thanks for pictures - really appreciate everyones help

 

I will try (almost) anything at the moment - so if you have any other ideas they are more than welcome

Temperature and Manifold Absolute Pressure Sensor (TMAP) measures the atmospheric pressure with ignition on and manifold vacuum pressure when engine is running as well as the manifold air temp

 

 

can't see it working very well covered in oil :) :D

Ill give the bu&&er a little bath in petrol and see what happens ??!!

[Dave-G]

Both mine and my mates have oil on them.

 

"Temperature and Manifold Absolute Pressure Sensor (TMAP) measures the atmospheric pressure with ignition on and manifold vacuum pressure when engine is running as well as the manifold air temp"

 

No wonder mine cost me

[scrote]

Its now geting worse - it seems that its running on 3 and a half all the time and it makes no difference what sensor i unplug or which tube i pull off - i get the same result every time i re-start. The only thing that looks like its ok is the turbo which cuts in and out with the engine every time i start up - even when its running rough.

 

The only good news i have is that i happened to attend my local Fraud Stealer on an unrelated work matter and got chatting to a salesman who has offered me a FREE diagnostic check which i hope to have done on monday.

 

I will post the results for all to see then

 

Wish me luck - please !!!! :D

[Guest bigal]

Hope you get it sorted and its not too expensive. :D

 

Cheers

Thanks Bigal - I hope you would have posted the same support knowing I am an OWL - if i knew how to id put the badge against my name

 

Scrote Owl Wednesday til i die - scummy blades are doomed ( i hope )

[Guest bigal]

Doesnt bother me who you support. After all my First team is Glasgow Rangers. I think the Owls could give them a run for their money at the moment. :D

Had my freebie fault test today with the main stealers who came up with two fault codes

 

P0301 ( which is appently a misfire on cyliner 1 )

P1666 ( Injector fault )

:( BUS IS BACK !!!! ????

 

had the engine top cover off - unclipped all the electrical connectors to the injectors (flimsie things - not your usual german engineering ?) - cleaned up the connections at the twist terminal on the right hand side of the cylinder head - and having just thrashed it up and down the A14 for a few miles all seems fine and dandy !!

 

The only trouble is that i did mess witha few things at once so if it happens again i dont know which to go to first.

 

It could all be just a coincidence but i cant beleive and injector can suddenly repair itself ? - ill let you know if it goes wrong tomorrow

 

BUT - the lesson here is - if you get told you have a faulty injector - dont go spending 500 notes untill you have checked all the wiring first - I phoned round a couple of diesel experts who were also trying very hard to sell me a full set of 4 recon units at 90 quid a throw plus labour stating " if one goes mate the others are sure to follow" - dont you just hate them !

 

Thanks for all your support

Ps - Now ive joined ill be visiting - problems with bus or not - i need a high score on the arcade for a start - and i am slightly technical so if i can help please shout !

[mumof4]

has it ever happened again scrote?

[scrote]

Thanks for asking MO4

 

Yes normally once a day when cold - need to take the turbo apart to clean it up and free the vanes and will do so when i have more time and the weathers a little warmer !

 

If anyone wants to come over to Suffolk and help me out for the day I wont say no.

[mumof4]

I would if i didnt have a crap sense of direction..besides,,gotta sort my wee beastie out first.LOL.

[Dave-G]

Aw - post 21 looked soooo promising. sure your current problem aint a glow plug mate?
