It's a slug!

[Andy]

OK, I give in, it's now got to the point where something has to be done - but what?

My 2000 Bravo JTD 105 has always seemed a bit slow of the mark since I bought it 3 years ago, it had 39000 miles on the clock (genuine)and would do 0 - 60 in about 14 secs.

Having read of other members using GPS and stopwatches to check their times, I have decided that the use of a sundial or candle might be more appropriate, as the 0 - 60 is now around 40 secs!!

The car now has 80,000 miles on the clock, the tyres are new and at the correct pressure, I have used injector cleaner 4 or 5 times in the last 3 years, and the air filter is OK. I usually record 55 - 58 mpg, no problems with the emissions during the MOT a few weeks ago, so where do I start?

Any suggestions that avoid spending more than the car is worth at the garage would be most welcome.

Andy.

14 seconds, something wrong, the bravo jtd when running correctly is one of the quickest diesels out there.

Does engine rev up past 3000rpm. If not then the Maf sensor could be faulty, I had this problem with mine. Also check for split hosesfrom the turbo. Is there any warning lights on the dash.

 

[Andy]

You could be right, it does tend to struggle once it gets to 3000, I'll check for split hoses first thing in the morning.

The glo plug light used to flash after startup, but this was cured after disconnecting the battery for an hour, all other warning lights have behaved themselves (most of the time)

Anyway, what do you mean "one of the fastest diesels out there"?!! So I've been driving around at half power (and full insurance premium) for the last 3 years - Aaaargh!

Seriously, thanks for your super fast response - cheers!

You can take the EGR valve pipe off, or block it up.... that gives you a bit.... OR it seriously slows it down if it's blosked and the pipe is connected.




There should be a clear pipe about centre along the black that goes under the plastic cover. it comes out of a vacume pump. if u take it off and block it up (screw a bolt into it) or just take it off... see if that helps it.

Re : it's a slug!

Thanks for the info Tommy, I've downloaded the info regarding the cleaning of the EGR valve and also the maf sensor, I'll also check out the hoses as you suggest. Also going to fit a new fuel filter, as the current one is well past it's sell by date.

That'll be me busy tomorrow, I just hope I get done before the match starts

Let you know how things turn out.

Thanks again.

Well my EGR was blocked and the pipe was off... this gained about 0.5sec 0-60 as it was only useing clean air not re-circulated exhaust gasses.


to changing the fuel filter, remove the electric plugs, 1's blue the other yeallow.... DO NOT PUT THEM ON THE WRONG WAY ROUND... apparently it's very very bad!!


then unclip the fuel pipes but don't remove them from the filter. then undo the 2 or 3 bolts that hold the filter on.


Put a towl / rag down the back of the engine, putt the filter away from the bolts and turn it on it's side (turn the top towards the battery) you can then unscrew it and remove it.


if you can do it quickly you shouldn't spill too much fuel - hence why you put a towl under it.

then tip the remainding fuel into the new filter and reverse the process.


I never had to bleed the system, just turn the key a few times to presurise the system and then after about 4 times start the car and give it full throttle!!!!


thats way, if there is an air lock hopefully the engine will keep running past the air bubble and self bleed.



easy lol

Once a slug!

Hi Ned and Tommy

Thanks so much for the advice, I've checked out both the EGR Valve and the MAF Sensor, giving both of them a good clean as per the docs downloadable on the site.

As a result, I've gone from having trouble keeping up with almost everything on the road, to .........

Wheelspin!!

Woohoo!!!!!!

all I need now is traction control lol

Fit a set of 18's... that soon slows you down!!!
