Product overview
VW Oil Pan
06A 103 603AJ is a oil pan in the RUIFAN VW range. It is one of 52 references in the VW Parts block and one of 136 across the catalogue as a whole.
It is supplied to aftermarket distributors, engine rebuilders and workshops, and can be quoted as part of a wider order covering other references in the same number family.
The part closes the bottom of the engine block, holds the oil when the engine is off and carries the drain plug and its thread. Flange flatness across the full perimeter is what decides whether it seals once it is fitted. The archived record for this reference holds the catalogue name, the vehicle brand block and the photograph; nothing further was stored, and nothing further is claimed here.
What this reference is used for
- Fleet and workshop stock for recurring service work
- Replacement of a dented, corroded or leaking pan
- Engine reconditioning and rebuild programmes
- Aftermarket catalogue coverage across a number family

Who it is for
Buyers Who Order This Reference
Aftermarket distributors
Warehouse distributors and wholesalers building coverage across a whole VW number family rather than a single fast mover.
Engine rebuilders and workshops
Reconditioning shops and independent workshops that need the correct reference on the bench rather than a near equivalent.
Importers and private label brands
Brand owners who sell under their own label and need the factory behind that label to stay the same from season to season.
Problems it solves
What Brings Buyers to This Part
- The drain boss thread has been stripped by repeated servicing and a thread insert is not an acceptable repair.
- A catalogue line has gone dead because the previous supplier stopped tooling this reference.
- The number is quoted under two or three different references in different markets and the buyer cannot confirm they are the same casting.
- The sealing flange on the old pan is no longer flat, so a new gasket alone will not stop the leak.

Materials and manufacturing
How This Oil Pan Is Produced
The archived record does not state a material for this reference. RUIFAN produces both drawn steel and cast aluminum parts of this type, and the correct construction is confirmed against the part being replaced before production is scheduled.
Confirm construction
Material and method confirmed against the part being replaced or a supplied sample.
Form or cast
Drawn from sheet, or die, gravity or sand cast, according to what the original part is.
Machine and finish
Sealing faces, bores and threads finished to the reference.
Inspect and pack
Checked against the reference sample, then packed with the sealing face protected.
Manufacturing methods listed here are the ones recorded on the original RUIFAN services page: deep and shallow draw stamping; die casting, sand casting and gravity casting; chrome plating and vacuum metallization. The method used for a given reference is confirmed against the part being replaced.
Quality control
Quality Systems Behind This Reference
RUIFAN recorded ISO 9001 and TS 16949 quality systems on its original site. Certificate numbers and validity dates were not stored in the archived material and are supplied on request rather than stated here.
Sealing flange
Flatness across the full perimeter decides whether the part seals at all. It is the first thing to check on arrival.
Drain boss
Thread condition and squareness to the boss face, checked before packing.
Dimensional check
Against the reference sample for the catalogue number being run.
Packing
Flange protection specified per programme, because a bent flange makes a sound part unusable.
Customisation
If This Reference Is Not Exactly What You Need
The original RUIFAN site stated that the factory develops oil pans and other aluminum castings from customer-supplied samples or drawings. That route covers references that never made it into the catalogue, superseded parts whose tooling has been scrapped, and private-label variants of an existing part.
A physical sample is enough to start. Where no sample survives, a dimensioned drawing or a 3D file works. Tooling cost, lead time and ownership are agreed in writing before any work begins.
What to send with an enquiry
- The number stamped or cast into the part being replaced
- The vehicle, the engine code and the production year
- A photograph of the flange face and one of the drain boss side
- Annual quantity, or the quantity for a first order
- Destination market, which affects packing and documentation
Comparison
06A 103 603AJ Against the Alternatives
How sourcing this reference from RUIFAN compares with the other routes a buyer has.
| Option | What you get | Where it falls short |
|---|---|---|
| RUIFAN catalogue supply | The reference held in a 136-number catalogue with the archive data published alongside it, produced in one plant with one packing standard. | Fields the original database never recorded are shown as not recorded rather than filled in. |
| Original equipment channel | Guaranteed fitment and full manufacturer documentation. | Highest unit cost, and older references are progressively withdrawn from supply. |
| Local pattern part supply | Short lead time and no import handling. | Coverage is usually limited to fast movers, so the long tail of a number family stays unsourced. |
| Used or reclaimed oil pan | Lowest purchase cost, sometimes the only route for a withdrawn reference. | Flange flatness, thread condition and corrosion are unknown until it is on the bench. |
Use guide
Identifying and Fitting 06A 103 603AJ
A working sequence for confirming the reference and fitting it without a repeat leak.
- Confirm the reference against the number cast or stamped into the part you are replacing, not against the parts system entry.
- Compare the archive photograph on this page with the part on the vehicle: flange outline, bolt count, drain boss side and overall depth.
- Check whether the application requires an oil level sensor boss. Two otherwise identical references can differ on this alone.
- Clean both the pan flange and the block face completely before fitting. Old gasket material and oil film are the usual cause of a repeat leak.
- Check the new pan sits flat against the block dry, before any gasket or sealant goes on.
- Follow the engine manufacturer's gasket or sealant specification. Do not add sealant on top of a moulded gasket.
- Torque from the centre of each long side outwards in at least two passes, and respect the sealant cure time before filling with oil.
Torque figures, sealant specification and gasket type are set by the vehicle manufacturer for the engine concerned. Follow that procedure rather than a generic figure.
Questions About 06A 103 603AJ
What vehicle does 06A 103 603AJ fit?
The archived catalogue record lists this reference in the VW Parts block. No vehicle application table was stored for this reference in the original database, so none is shown. Send the vehicle, the engine code and the number from the old part and we will confirm against the catalogue before quoting.
What quality systems does the factory work to?
The original RUIFAN site recorded ISO 9001 and TS 16949. Current certificate numbers and validity dates are not published here because they were not in the archived material; they are provided on request.
What are the minimum order quantity and lead time for 06A 103 603AJ?
Minimum order quantity, carton quantity and lead time were not recorded in the archived catalogue and are confirmed per order, because they depend on whether the reference is being run on its own or alongside other lines in the same family.
Do you have cross reference numbers for this part?
No alternate numbers were stored against this reference in the original database, so none are published here. Twenty of the 136 catalogue records do carry recorded alternates. If you hold a number you believe matches this part, send it with a photograph and we will check.
What is 06A 103 603AJ made from?
The original catalogue record did not state a material for this reference, so none is published. RUIFAN produces both drawn steel and cast aluminum parts of this type, and the correct construction is confirmed against a sample or the part being replaced before quoting.
