No Boost

[Soarer]

Hi All

I am after some advice please. I have a 12 Plate Berlingo Van, 1.6HDi, 75bhp. Slow but reliable we thought, never let us down, etc. We thought it was running great until about 3 1/2 Months ago, then we realised there was a problem. 3 1/2 months ago I bought a 58 Plate Partner 1.6HDi 90bhp, the difference in performance was ridiculous, far more mpg and noticeably quicker than the newer Berlingo. I then had the Puggy remapped to 116 bhp which transformed it even further away from the Berlingo, achieving 70mpg on a 480 mile trip loaded up, the Berlingo gets about 32mpg. So 2 weeks later in went the Berlingo for a remap to 116bhp as well. The garage said from the start that the Berlingo seemed slow, we told them it’s probably because it’s carrying some weight, so they remapped it to the same spec as the Puggy. On picking the Berlingo up the guys at the garage said agin that they were not happy with the Berlingo, but to try it out and let them know. The remap difference was hardly noticeable if any different at all, we emptied the van out to lighten it and tried again, no difference that we could tell, maybe a slight difference in 1st and 2nd gear but very little if any. We took it back in and they had a good test drive in it and they think that it’s not getting any boost, which would explain why it has always been slow, they said that even the 75bhp Berlingo have a nippy feel about them, something that ours has never had. 

I know on our older Partner there is a vacuum pipe that has to be securely in place, or you get no boost (found that out the hard way), but the Newer Berlingo doesn’t have that type of set up. The Berlingo has a full service history, it had 62K on it when we bought it 17 months ago, it’s now done 96K, but it has always been slow, we thought it was normal as it only had 75bhp, and we have never driven a Berlingo before so had nothing to compare it against. 

Is there anything I could check on the Berlingo that will stop it giving boost, while the UK is on shut down, as we won’t be going to work for the next few weeks. The air intake seems clean and free flowing, the inter cooler pipes are all in good condition and free flowing. Is there some sort of electrical valve or vacuum valve that needs looking at, similar to our older Partner. Any advice will be greatly appreciated.

Kind Regards

Check pipes to turbo wastegate.
Or better check if wastegate is operational.
This is for different car but this is the correct procedure.

You may have a faulty MAF. Are there any error codes?

Hi

Thank you for your reply. The video was great and made perfect sense. I will have a look at it tomorrow.

Hi

Thank you for your reply. I don't know if it has had error code to be honest, but it will have at the moment. Just at the end of last week it started to show an engine fault symbol in the clock cluster, and the centre display started to say that the following: -

ENGINE
FAULT

RISK OF FILTER
CLOGGING

P FILTER ADD
LEVEL LOW

Do you know what all that means by any chance. I will buy a MAF Sensor for it though, as I have noticed that they are not excessively expensive. Thanks again

Kind Regards

Your problem described above is to do with the DPF & probably not the MAF. If you do decide the by a MAF, beware of cheap copies.

How many miles has it done, do you often do short journeys?

Hi

Thanks again for your reply. 

The van has now done 96K in 8 years, in the last 17 months it has done about 30K, since I bought it. It does a mix of journey types, some are fairly short of about 15 miles, the rest is generally about 60 miles. About once every 3 weeks we drive it in a lower gear to keep the revs up over a mile or so when the engine is warm. We do this as we had heard that you need to blast the loose crap out of the DPF about once a month. Our cars are all petrol, we have never owned a diesel vehicle before. 

Kind Regards

Hi Tom,

Sustained cruising on the motorway at 65 in 4th for 15 minutes (without dropping below 65 or exceeding 70 or changing gear) should initiate a DPF regen cycle. The blasting-the-crap-out is a bit of a myth, the ecu starts a regen cycle only under limited conditions. Diesel soot is sticky, it doesn't blow out, needs to be burned off at high DPF and CAT temperatures way above the normal running values. The ecu does this by injecting extra fuel into the system to raise exhaust gas temps (EGT's) to extreme levels when required.

But, your Eolys additive tank level is reporting low, so that won't help to begin with. Sounds like your DPF soot levels are high and if it clogs completely, the ecu will put you into limp mode. Once that happens, only a forced regen using a diagnostic tool capable of initiating a standing clean, will work. This should not be done on a grassy area as it raises the CAT and DPF temps to nearly 1000 degrees and it can start a fire. Look into DPF forced regen online.

Hi,

This video is for the same engine 1.6 HDI

Hi Zion

Thank you for replying with the information. Unfortunately for me a DPF Regen Cycle will be hard to achieve as I don't have the opportunity to get my van to cruise at that speed in 4th gear for that length of time, I live in the North East of Scotland, the nearest Motorway to us is 125 miles away just to the South of Perth, the nearest Dual Carriageway to us is no more than a 10 mile stretch but it is 45 Miles away in-between Inverurie and Aberdeen and the longest stretch on it is about 4 miles at best before you get to a round-a-bout.

You mention my Eolys Additive Tank Level being low, where will I find the Eolys Additive Tank filling cap, what do I need to put into it to fill it back up to the level it should be, and where can I buy it from. Sorry for so many questions, I didn't know any of what you have informed me. We also have a 58 Plate Peugeot Partner, 1.6HDi 90bhp, will this also have a Eolys Additive Tank, or is this something that the later models have such as my 12 Plate Berlingo.

Kind Regards

Tom
