Let’s repair a Simos PCR 2.1 ECU!

The Simos PCR 2.1 ECU can be found in many different models of VAG (Audi, Seat, Skoda and VW). In some cases faults are reported that have to do with the control of the injectors. Often it turns out not to be a fault in the ECU but elsewhere. We will explain below why.

Common faults and fault codes

The Continental Simos PCR2.1 is a VAG ECU that we see in for example the Volkswagen Polo 6R/6C, the Golf IV and the Caddy III. An often seen fault description on the remanufacture order form is the loss of control on one or more of the injectors. When testing the ECUs, we quite often find though that the control of the injectors operates normally. The feedback that we receive from our customers helped us find the solution to this fault!   

Nearly always, the cause of this problem is found due to discontinuity or too much resistance in the wiring. Especially the loom leading to the injectors needs to be verified thoroughly. The connectors on the injectors themselves do cause problems as well verify these. If the wiring and the injectors are working as they are supposed to, then it is possible that the fault is caused by the Simos ECU.

Fault codes for injector circuits in VAG petrol engines with a Simos ECU (manufactured between 2001 and 2008):

  • 16585 / P0201 Cylinder 1, Injector Circuit Fault (N30)
  • 16586 / P0202 Cylinder 2, Injector Circuit Fault (N31)
  • 16587 / P0203 Cylinder 3, Injector Circuit Fault (N32)
  • 16588 / P0204 Cylinder 4, Injector Circuit Fault (N33)

1. Log in or create an account

ACTRONICS works exclusively with car companies, brand dealers and specialists. You need an ACTRONICS account to place an order. Our customer service will assess whether your account is approved based on the information you have entered.

2. Find your part and create an order

Select your vehicle at the top of this page and choose the part number that you can read on the part. Can't read the OE number? Then select the option "OE number is not in the list" on this page. Can't find the part? Then request a quote.

3. Enter your diagnostic information and order details

When you register a revision order, we ask for more information about your diagnosis, such as your observations and/or an error code. This helps us to carry out the revision. After this, you choose your shipping and payment preference and start the order.

4. Packing & shipping

Make sure the part is securely packed so that it is not damaged during transport. Have you chosen our pick-up service? Then we will ensure that the part is picked up from you. This happens on working days (between 08:00 and 18:00) often within a few hours. Have you chosen to ship it yourself? Then bring the package to a parcel point near you. In both cases, you will receive instructions from our customer service.

5. We test the part

We test and inspect your part as soon as it arrives with us. Then we start the revision. Sometimes our test shows something different than the diagnostic information. In that case, we will contact you and share our findings and diagnosis. We only charge test costs for this and no revision costs.

6. We revise the part

Our specialists revise your part. You will receive updates so that you are always aware of the status of your order. If your part has successfully passed our final test, we will ship it to you. If necessary, we will provide additional workshop instructions and tips.
