2.0 BiTDi Engines. What to know!

2.0 BiTDi Engines. What to know!

The idea of a 2.0 BiTDI Transporter or Amarok sounds great, and with quoted figures from the factory round the 180bhp mark, it sounds like the perfect platform to start with, right...?  

Whether you already own a vehicle with one of these engines or thinking of buying one, this blog is well worth a read.

Factory Figures

The first thing to note when it comes to these engines are the quoted power figures from factory. Since the first one we tuned to date, we have yet to see one of these engines make stock power figures on our dyno. Most are producing anything from 10-20% lower than the book figures.

The graphs below show an Amarok and Transporter both with the 2.0 BiTDi 180bhp


Although the stock figures are not what they seem, remapping is the best way to regain what you think you had.

We normally expect to see around 15-20% gain over whatever they pull standard.

The exception to this are the later Transporter 199 & 204bhp engines. Starting with the 204bhp models, although these also under read as standard, tuning makes a much bigger difference, usually producing around 230/240bhp with a custom tune (Graph Below).

It get's better...
If budget allows (Starting from ~£42,000!), the latest 199bhp models seem to be the cream of the crop and the one to have in terms of what power can be achieved. The ones we have tuned so far do close to the stock figures, which is impressive in itself based on previous models, but what is even more impressive is what they can do with a tune. A custom remap with all stock hardware would see you at around 250-260bhp! (Graph Below).


A lot of people swap to all terrain tyres which is great for building sites and wild camping but when it comes to the dyno these can have large affects to the power figures.

The graph below compares regular Continental Vanco Contact van tyres vs General Grabber AT3 tyres on the same stock van with no other changes. Other more ‘off road’ tyres can have larger affects than this so is worth bearing in mind when on a rolling road.


Common Problems

The Transporter CFCA engine suffers with a problem with the EGR cooler (Google search CFCA EGR cooler, you'll find plenty of information!)

Before carrying out any tuning work we would recommend a compression test to ensure the engine is healthy, unless you are aware of the issue and have already taken preventative measures.

Compression Specifications:

Normal - 362 – 450 PSI
Min – 275 PSI
Maximum difference between cylinders – 75 PSI

We are now only offering tuning on the CFCA engines after a compression test has been carried out. We can offer this service from £150+ VAT on top of the tuning prices. (You would need to book in with us in advance)

Generally, our customers request us to remove the EGR cooler, blank the EGR and the remove the DPF to stop the DPF from becoming blocked. This is done to prevent irreversible damage caused by the CFCA EGR cooler failing.

Later Transporter 204bhp/199bhp and Amarok engines do not have the same EGR issues so we do not require a compression test before tuning.

If caught early enough and a compression test comes back ok, the EGR cooler can just be replaced for a later 'D' revision part that does not have the same issues. This latest revision EGR cooler is available in both Genuine and Peirburg (who manufacture the genuine ones):

Too Late?

For those not so lucky to catch it early, we now offer a full brand new genuine CFCA engine swap service. This is ideal for those happy to keep the van in its original spec. We can still offer our usual tuning and modifications but for obvious reasons this would void all warranty on the new parts.
This service comes complete with the following brand new parts needed to meet the requirments for the 2 year warranty;

**Please note, when swapping the engines on these vehicles, other parts are required to be removed. We can not always guarantee that some of these parts will be easily removed, and normally some parts may have become seized. This may result in further parts and labour costs if these parts cannot be salvaged**

Darkside Developments accepts no responsibility for the use of EGR / DPF removal parts on the public highway where removal of emissions controls is prohibited. It is the customers responsibility to ensure they comply with rules and laws relating to their home country
