Before you buy a used Opel Omega B.
Taken only from Testigo's sourced sheets. Use it to question the seller and on the test drive: it does not confirm that any particular car is affected.

The essentials.
- 1 documented, sourced fault across its 2 engines.
- That is not much data: if no other faults show up here, it does not mean it has none.
- It only applies with certain equipment or production dates: ask what this car has.
- We have no official recalls on record for this model; ask anyway, with the chassis number (VIN).
- According to the data we have, all its engines have the same number of documented faults.
Typical faults by engine
The period and mileage are those mentioned by each sheet's sources. They are not a maintenance interval and do not predict that any particular car will fail.
All versions
Sheets the catalogue links to all 2 of its engines.
- Omega B rain-sensor relay failureElectrical and electronic systems
- Period mentioned
- Bulletin-specific period and equipment stated in each assignment.
- Mileage mentioned
- The sheet does not mention a mileage.
Applies if: Only Omega B built 05/2000–05/2002 with automatic wipers/rain sensor; check the version of both relays. HELLA indicates modified relays from VIN W0L0VBF6921061034; do not attribute automatically to later units.
2.2 / 2.6 / 3.2 V6 · 2.2 / 2.5 DTI
2.2 / 2.6 / 3.2 V6 (Petrol) · 2.2 / 2.5 DTI (Diesel)
We have no faults specific to this engine, only those common to every version.
Which engine has the fewest documented faults?
| Engine | Documented faults |
|---|---|
| 2.2 / 2.6 / 3.2 V6Petrol | 11 with conditions |
| 2.2 / 2.5 DTIDiesel | 11 with conditions |
According to the data we have, all its engines have the same number of documented faults.
We only count the sourced sheets we have. An engine with fewer is not guaranteed to be more reliable: it may have been studied less or sold in smaller numbers.
Official recalls: ask before you pay
We have no official recalls on record for this model. Our list is not complete: ask anyway, with the chassis number.
- Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
- Ask an official Opel dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
- Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.
On the test drive: what to look and listen for

Electrical and electronic systems
Look out for: Automatic-wiper function fails.
Ask them to check: Check both engine-bay relays and replace where required; HELLA also calls for replacement if sensor electronics are diagnosed faulty.
