The 445110369 fuel injector from Bosch is designed for Common Rail use in the 2.0 TDI and directly affects combustion quality, cold-start behavior and engine running. Before replacing, the reference number and vehicle data must be matched against the old part.
1) Part number, manufacturer and catalogue/cross-references
The fuel injector with reference 445110369 comes from Bosch and is intended for precise fuel metering in the Common Rail system. In practice, the reference number 445110369 and the comparison/catalog numbers 0 986 435 166 and BOSCH 0 986 435 166 are used for part assignment, because the housing and coding versions can differ depending on the engine variant.
Vehicle assignment is done via TecDoc compatibility data and the vehicle widget; in doing so, the engine code letters and the old-part information should be checked against the part numbers 445110369, 0 986 435 166 or BOSCH 0 986 435 166. Even small deviations in injection quantity or spray pattern can lead to noticeable changes in engine running, fuel consumption and power delivery in Common Rail operation.
2) Vehicle compatibility: VW/Audi 2.0 TDI (models with the listed time period)
The 445110369 fuel injector is stored in the TecDoc data for 2.0 TDI variants from the VW/Audi group environment; the following models are listed as compatible base. The exact version must be verified on the old part using reference number 445110369 and the comparison numbers 0 986 435 166 or BOSCH 0 986 435 166.
| Vehicle | Engine | Model years (per list) |
|---|---|---|
| AUDI A1 (8X1, 8XK) | 2.0 TDI | 05/2012-04/2015 |
| AUDI A1 (8X1, 8XK) | 2.0 TDI | 09/2011-04/2015 |
| AUDI A1 Sportback (8XA, 8XF) | 2.0 TDI | 05/2012-04/2015 |
| AUDI A1 Sportback (8XA, 8XF) | 2.0 TDI | 09/2011-04/2015 |
| AUDI A3 (8P1) | 2.0 TDI | 03/2006-08/2012 |
| AUDI A3 (8P1) | 2.0 TDI | 05/2003-08/2012 |
| AUDI A3 (8P1) | 2.0 TDI 16V | 05/2003-08/2012 |
| AUDI A3 (8P1) | 2.0 TDI 16V quattro | 08/2004-08/2012 |
| AUDI A3 (8P1) | 2.0 TDI quattro | 03/2006-08/2012 |
| AUDI A3 Cabriolet (8P7) | 2.0 TDI | 04/2008-05/2013 |
3) Fit checks and installation notes before replacement
Before ordering and before installation, the reference number 445110369 must be matched against the old part; alternatively, the assignment is verified via 0 986 435 166 or BOSCH 0 986 435 166. The reason is design-related: Common Rail injectors are matched to defined fuel metering and a suitable spray pattern, and deviations lead to rough running.
When matching, especially the engine code letters and the vehicle data from the vehicle widget are relevant, because the TecDoc compatibility data only reliably identify the correct variant when the engine and component number match. During removal and replacement, make sure the 445110369 injector is installed in the intended mounting design, because pressure and quantity deviations during operation directly affect combustion quality, cold start and engine running.
4) Typical symptoms and selection criteria for Common Rail fuel injectors
A fuel injector in the Common Rail system directly affects combustion quality, cold-start behavior, engine running, fuel consumption and power delivery. If injection is no longer exact, even small deviations in pressure, injection quantity or spray pattern are enough to make the engine run rough.
For selecting the correct fuel injector, the reference number 445110369 is the key criterion; the comparison numbers 0 986 435 166 and BOSCH 0 986 435 166 serve as additional assignment in the catalogue context. The decision should not be based only on vehicle data, but always on matching the part numbers on the old part, because the 2.0 TDI engine family may require different injector variants depending on the configuration.

Frequently Asked Questions
Which reference number do I need to check on a Bosch 2.0 TDI fuel injector?
For the Bosch fuel injector, the reference number 445110369 is decisive. in the catalogue context the comparison numbers 0 986 435 166 and BOSCH 0 986 435 166 are used. Before replacement, the reference number, engine code letters and vehicle data should be matched against the old part.
How can I tell that a Common Rail fuel injector is no longer metering correctly?
Typical signs are rough engine running and noticeable issues with cold-start behavior. Since the fuel injector directly affects combustion quality, fuel consumption and power delivery, deviations in injection quantity or spray pattern often lead to noticeable driving and running differences.
Can I select a fuel injector only based on vehicle model and model year?
TecDoc compatibility data provides a starting point, but safe selection is done by matching the part numbers on the old part. The reference number 445110369 and the comparison numbers 0 986 435 166 or BOSCH 0 986 435 166 must match the specific engine variant.
What happens if the pressure or spray pattern of a fuel injector deviates?
Even small deviations in pressure, injection quantity or spray pattern are enough for the engine to run rough. This directly affects combustion quality, cold start and the entire engine running.
Which Audi models with 2.0 TDI are listed for 445110369?
In the listed compatibility list, among others Audi A1 (8X1, 8XK) 2.0 TDI and Audi A3 (8P1) 2.0 TDI/16V/quattro and Audi A3 Cabriolet (8P7) 2.0 TDI are named. The production date ranges are given for each model in the table; the final fitment is verified via 445110369 and the comparison numbers.
