Replaces all seven shift solenoids on the ZF 5HP19 five-speed automatic to clear harsh shifts, limp mode, and solenoid fault codes.
If your BMW 325i, 330i or 525i, Audi A4, A6 or allroad, or Porsche Boxster or 996 with the five-speed Tiptronic or Steptronic automatic has started banging into Drive, thumping on coast-down or dropping into limp mode with a solenoid fault stored, this is the complete ZF 5HP19 solenoid set: three green-connector shift solenoids, three black-connector pressure regulators and one yellow-connector pressure regulator, seven pieces in all. Replacing the whole set together means the valve body comes out once instead of every time the next tired coil gives up.
The 5HP19 is fully electronic. The three green-tab parts are on/off shift solenoids (often called MV1 to MV3) that the control module switches to move the shift valves between gears. The four remaining parts are proportional pressure regulators (EDS solenoids) that the module pulses to set modulating pressure, main line pressure and the apply and release pressure of the individual clutches during each shift. The yellow-tab unit is the EDS 1 regulator, and it matters more than its size suggests: in an ATSG technical bulletin, Wayne Colonna explains that a mechanically sticking EDS 1 raises modulating valve pressure, which drives up line pressure and accumulator back pressure. The result is the classic 5HP19 complaint of a firm engagement into Drive and harsh coast downshifts that get worse as the fluid heats up, seen most often on 2003 and later vehicles.
Scan the transmission module with a tool that reads BMW, VAG or Porsche transmission faults rather than generic engine codes, and note which solenoid is named. Then measure each solenoid circuit at the case connector and compare the readings to the specification for your vehicle; our guide to testing a transmission solenoid with a multimeter walks through the method. If one circuit reads open or shorted at the case but the solenoid itself is good on the bench, the fault is the internal harness, which is sold separately as a 5HP19 internal wiring harness. If all seven read correctly and the harsh shift persists, ATSG advises checking that the modulating pressure valve moves freely in its bore, which is a valve body issue rather than a solenoid issue.
This set is listed for the 5HP19FL and FLA used by Audi and Volkswagen (the 01V transaxle in the B5 and B6 A4, C5 A6, B5 S4 2.7T and B5 Passat) and the 5HP19 and HL/HLA versions used in the BMW E46 and E39 and the Porsche 996, 986 Boxster and 987. Two cautions. First, BMW fitted both the ZF 5HP19 and a GM five-speed in the same E46 and E39 years, so read the tag on the side of the transmission before ordering. Second, Wikipedia notes that 1999 Audi FLA units used induction speed sensors while 2000-on units use Hall effect sensors, and ATSG lists two different EDS 1 part numbers for those two styles. The yellow solenoid in this kit is ZF 0501210725, which ATSG lists for the Hall effect and 2003-up units. The green solenoids cross to 0501316463 and the black to 0501210019.

It fits the E46 and E39 only if the car has the ZF 5HP19. BMW also used a GM five-speed in the same years, so check the identification tag on the transmission case. If it reads 5HP19, this set applies.
The coils and valves in a 5HP19 age together. Replacing only the one that set a code often means pulling the valve body again a few months later. Doing the full set once also restores matching pressure control across all clutches.
ATSG ties that complaint to a sticking EDS 1 pressure regulator, the yellow-connector part in this kit. It raises modulating, line and accumulator pressure, and the condition gets worse when hot.
Maybe not. 1999 FLA units used induction speed sensors and ATSG lists a different EDS 1 part number for those early units. The yellow solenoid here is the later Hall effect / 2003-up version. Send us your VIN before ordering for a 1999 car.
Yes. Install a new filter and pan gasket, fill with the ZF-approved fluid for your vehicle at the correct temperature, clear the stored faults and reset the transmission adaptations with a capable scan tool, then road test through every gear.
