Hi People,
new here and new to being a TD5 owner.
I've had my 2006 37k TD5 a month and have never floored it to see the true power. I drove it back from Scotland and it reached 75mph no probs although i let it build gradually and never floored it. It still felt ok though, not lack of power id say.
Upon cleaning my engine i noticed the MAF was full of dirt and the gauze was bent and broken. I cleaned and straightened. This then made my landy not go over 50mph and feel like the turbo wasn't cutting in. I unplugged the MAF and it went like stink.
No warning lights at all with the MAF plugged in our out.
Then after 1 week of running unplugged the power has reduced all of a sudden? Very noticable, the turbo seemed to cut in low revs and now hardly but still does cut in. I have no rev counter.
Anyway the new MAF arrived,
Fitted a Bearmach MAF and I thought it would run better than unplugged but seems held back somewhat, not as bad as not reaching 50mph, it will still do 70-80 no probs but there is not the performance i was expecting.
I really felt the turbo when i put my foot down on my 300TDI.
Being a Scania Master Tech I Know the importance of sensors etc but I have no equipment whatsoever to see what is happening.
The MAP is clean, the wastegate moves, the EGR moves, it looks very clean inside, no pipes appear perished or broken. Air filter, air filter box and trunking are clear.
Am i missing something, is this how TD5's are?
Are they better Re-mapped or defaulted ECU maps when sensors are unplugged?
I have also unplugged the 2 Vaccum valve plugs which didn't bring a light on but did make a little difference in power/turbo cut in at lower rev range with new MAF than when plugged in.
My main query is;
1. Why do no warning lights come on when plugs are unplugged?
2. Why did my TD5 run super with the MAF unplugged but then after a week all of a sudden start to lack power again?
3. With my new MAF fitted, is this power output standard? Will reach 70-80 but just seems lacklustre?
Many thanks to people with more landy experience than myself
